# Writing Formulas When we know there is an explicit relationship between two quantities, often we can write a formula to express the relationship. For example, suppose that a toll of $3.75 is collected from each vehicle that crosses a particular bridge. Let A be the total amount of money collected, and let c be the number of vehicles that cross the bridge on a given day. Then, A =$ 3.75 c is a formula that expresses the total amount of money collected from vehicles on any given day.Write a formula for the situation. Include as part of your answer a list of variables that were used, and state what each variable represents.A parking garage charges $7.50 for the first hour and$ 5.25 for each additional hour. Write a formula to represent the parking charge for parking in this garage for h hours. Assume h is a counting number greater than 1 .

To determine

To write : a formula for the situation. Include as part of your answer a list of variables that were used, and state each variable represents.

A parking garage charges $7.50 for the first hour and$5.25 for each additional hour. Write a formula to represent the parking charge for parking in this garage for h hours. Assume h is a counting number greater than 1.

Explanation

Given information : When we know there is an explicit relationship between two quantities, often we can write a formula to express the relationship.

For example, suppose that a toll of $3.75 is collected from each vehicle that crosses a particular bridge. Let A be the total amount of money collected, and let c be the number of vehicles that cross the bridge on a given day. Then, A=$3.75c is a formula that expresses the total amount of money collected from vehicle on any given day.

The given situation is “A parking garage charges $7.50 for the first hour and$5.25 for each additional hour. Write a formula to represent the parking charge for parking in this garage for h hours. Assume h is a counting number greater than 1
