A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)

Answers

Answer:

The number of customers that would need to come in the café for the company to break even is 470.

Step-by-step explanation:

Given

Revenue = y = 10x ……………….…. (1)

Cost = x = 4,700 + 2x ……………… (2)

Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:

10x = 4,700 + 2x

10x - 2x = 4,700

x = 4,700 / 10

x = 470

Therefore, the number of customers that would need to come in the café for the company to break even is 470.

Find the nth term of this quadratic sequence 3,8,15,24,35...

Answers

Answer:

n^2 + 2n.

Step-by-step explanation:

n       =       1     2     3     4     5

term t =     3    8     15   24   35

Diffs  =          5    7      9     11

                        2     2     2             - so the nth term contains n^2.

n^2   =       1     4      9    16    25

t - n^2 =    2    4      6     8     10

This is an arithmetic sequence with nth term = 2 + (n-1)2 = 2n

So the nth term of the quadratic sequence = n^2 + 2n.

The frequency,f kilohertz of a radio wave is inversely proportional to its wavelength, Ym. The frequency of a radio wave that has a wavelength of 3000m is 100 kHz. Find (i) The frequency of a radio wave that has a length of 500m (ii) The wavelength of a radio wave that has a frequency of 800kHz

Answers

Step-by-step explanation:

The frequency of a radio wave that has a wavelength of 3000m is 100 kHz

(a) Wavelength = 500 m

We know that,

[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{500}\\\\f=600\ kHz[/tex]

(b) Frequency, f = 800 kHz

[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{800\times 10^3}\\\\\lambda=375\ m[/tex]

Hence, this is the required solution.

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest interest rate.

Answers

Answer:

Interest rate = 2.41%

Step-by-step explanation:

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.

The formula to calculate the Interest rate for a Compound Interest is given as:

Solving for rate r as a decimal

r = n[(A/P)^1/nt - 1]

r = 12 × [(305.33/240.00)^1/(12)(10) - 1]

r = 0.0240996

Then convert r to R as a percentage

R = r * 100

R = 0.0240996 * 100

R = 2.41%/year

Therefore, the Interest rate = 2.41%

Jackson is starting an exercise program.The first day he will spend 30 minute on a treadmill by 2 minutes each day.Write an equation for t(d),the time,in minutes,on the treadmill on day d

Answers

Answer:

For the d day Jackson exercised for t(d)=  30 + 2d where d is the number of day.

t(d)= 30 + 2d

Step-by-step explanation:

Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0  and so on.

Therefore

For the first day Jackson exercised for  30 minutes

y= 30 + 2x

y= 30 + 2(0)

y= 30 minutes

For the second day Jackson exercised for (x=1) 32 minutes

y= 30 + 2x

y= 30 + 2(1)

y= 32 minutes

For the third day Jackson exercised for (x=2) 34 minutes

y= 30 + 2x

y= 30 + 2(2)

y= 34 minutes

For the fourth day Jackson exercised for (x=3) 36 minutes

y= 30 + 2x

y= 30 + 2(3)

y= 36 minutes

For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.

y= 30 + 2x

y= 30 + 2(d)

y= 30 + 2d
