A store has 125 scientific calculators.
Brand x sells for $20 each; Brand y sells
for $15 each. If the total selling price
of the calculators is $2,275, how many
of each calculator does the store have?
Answer:
Brand x: 80
Brand y: 45
Step-by-step explanation:
x + y = 125
20x + 15y = 2275
-20x - 20y = -2500
(+) 20x + 15y = 2275
--------------------------------
-5y = -225
y = 45
x + y = 125
x + 45 = 125
x = 80
Answer:
Brand x: 80
Brand y: 45

Joseph asks 10 of his friends how many baseball trading cards each friend has.
The data is shown in the dot plot. How many friends have more than five cards?

10
4 5 6 7
baseball trading cards
11
A. 3
C. 10
B. 5
Answer:
2 friends have more than 5 cards
Step-by-step explanation:
Incomplete question;
I will answer this question with the attached dot plot
The horizontal axis represents the friends, the vertical represents the number of baseball trading cards and the dots represent the frequency
So, we have:
[tex]Friend\ 1 = 2[/tex]
[tex]Friend\ 2 = 3[/tex]
[tex]Friend\ 3 = 7[/tex]
[tex]Friend\ 4 = 4[/tex]
[tex]Friend\ 5 = 2[/tex]
[tex]Friend\ 6 = 6[/tex]
[tex]Friend\ 7 = 2[/tex]
[tex]Friend\ 8 = 5[/tex]
[tex]Friend\ 9 = 1[/tex]
[tex]Friend\ 0 = 0[/tex]
The friends that has more than 5 are:
[tex]Friend\ 3 = 7[/tex]
[tex]Friend\ 6 = 6[/tex]
Hence, 2 friends have more than 5 cards
7. Would you expect the world population growth to be best modeled be a linear, quadratic, or exponential function?

Ben opened a savings
account with $75,
Every week he added
$20 more. Write on
equation to model this
situation.
Answer:
The equation would be y = 75 + 20x
What is the solution to the system of
equations graphed below?
a.(-13,-20)
b.(-15,-22)
c.(-1,-8)
d.(-10,-15)
Answer:
(-13,-20)
Step-by-step explanation:
We know that the graph with x-intercept at (7,0) and y-intercept at (0,-7) is y = x-7
and the second equation is y = 2x+6
Therefore, we have two equations.
[tex] \large{ \begin{cases} y = x - 7 \\ y = 2x + 6 \end{cases}}[/tex]
Because both equations are equal (y=y)
x-7=2x+6
-7-6=2x-x
-13=x
We know the value of x, but not y-value. We substitute the value of x to get the value of y.
Substitute in any given equations which I will be substituting in the first equation.
y=-13-7
y = -20
Therefore when x = -13, y = -20
In coordinate form, we can write as (-13,-20).

Solve the inequality -5(x - 1) > -40, and graph the solution on a number line.
Answer:
x<9
Step-by-step explanation:
-5(x-1)>-40
x-1>-40/-5
x-1>8
x>8+1
x>9
x<9
The solution of the inequality - 5(x - 1) > -40 will be;
⇒ x < 9
And, The solution of the inequality is shown in number line.
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ - 5(x - 1) > -40
Now,
Solve the inequality as;
The inequality is,
⇒ - 5(x - 1) > -40
⇒ - (5x - 5) > - 40
⇒ 5x - 5 < 40
Add 5 both side,
⇒ 5x - 5 + 5 < 40 + 5
⇒ 5x < 45
Divide by 5, we get;
⇒ x < 9
Thus, The solution of the inequality - 5(x - 1) > -40 will be;
⇒ x < 9
And, The solution of the inequality is shown in number line.

Principal = $47,300 Rate = 3% Time = 4 months What will the total payment plus interest be?
Answer:
Simple Interest (I) = Principle * Rate * Time
so I = PRT
P = $47300
R = 3% = 0.03
T = 4months = 0.33years
so
Assuming its per year after 4month
I = (47300)(0.03)(0.333333)
I = 472.999527
I = $473
Now we'd add the interest(I) to the Principle
$47300 + $473 = $47773.00
Assuming it is per month, after 4months
I = PRT
I = (47300)(0.03)(4)
I = $5676.00
Now add the interest to the principle
$47300 + $5676 = $52976.00

A woman bought a bag of rice 5700 naira and in 3 weeks later, she could only buy 2/4 of the bags for 5700 naira. Find the percentage?
Answer: 100% increase
Step-by-step explanation:
You need the find the cost per bag in those weeks.
Three weeks ago, she could buy a bag for N5,700.
Three weeks after that, she could only buy half a bag for the same amount. A bag therefore costs:
= 5,700 ÷ 2/4
= N11,400
The percentage increase is:
= (11,400 - 5,700) / 5,700
= 100%
