Linda needs to have her car towed. Little Town Auto charges a flat fee of $75 plus $2 per miletowed. Write a function expressing Linda's towing cost, C, in terms of miles towed, x. Find thecost of having a car towed 14 miles.

Answers

Multiple 14•2=28 then add 75+28=103 she will Pay 103

The cost of having a car towed 14 miles is $103.

To express Linda's towing cost, C, in terms of miles towed, x, we can use the given information that Little Town Auto charges a flat fee of $75 plus $2 per mile towed.

The function for the towing cost, C, can be written as:

C(x) = 75 + 2x

Where x represents the number of miles towed.

To find the cost of having a car towed 14 miles, we substitute x = 14 into the function:

C(14) = 75 + 2(14)

C(14) = 75 + 28

C(14) = 103

Therefore, the cost of having a car towed 14 miles is $103.

To amend a country's constitution 7/9 of the 69 states in that country must approve the amendment. If 52 states approve an amendment will the constitution be amended

Answers

Answer:

Constitution will not be amended.

Step-by-step explanation:

To amend the country's constitution, number of states should approve the amendment = [tex]\frac{7}{9}[/tex] of 69

= [tex]\frac{7}{9}\times 69[/tex]

= 53.67

≈ 53 states

But the states who approved the amendment = 52

And 52 < 53

Therefore, constitution will not be amended.
