Question

A therapist charges $369 office three and $4.50 a minute. Write an equation to find the total cost y, after x,the number of minutes?,

Answer 1

Total cost= 369 + 4.5x

x= number of minutes

Explanation:

Giving the following information:

Fixed cost= $369

Unitary variable cost per minute= $4.5

To calculate the total cost after x minutes, we need to use the following formula:

Total cost= 369 + 4.5x

x= number of minutes

For example, for 45 minutes:

Total cost= 369 + 4.5*45

Total cost= $571.5
