Question

Isabella is deciding between two parking garages. Garage A charges an initial fee of

Answer 1

Answer:

1. A = 4 + 3t ............ 1

  B = 12 + 2t .............. 2

2. 8 hours

Step-by-step explanation:

For park A,

A = 4 + 3t ............ 1

where A is the amount paid, and t is the number of hours.

For park B,

B = 12 + 2t .............. 2

where B is the amount paid, and t is the number of hours.

The hours that would make A = B can be determined as follows.

Equate 1 and 2, so that;

A = B

4 + 3t = 12 + 2t

collect like terms

3t - 2t = 12 - 4

t = 8

The number of hours that would make the cost of each garage the same is 8.

Answer 2

Answer:

A= 3t+4

B= 2t+12

3t+4=2t+12

t= 8 hours
