Answer:

1. $18.90

2. Every statement is true EXCEPT e

Step-by-step explanation:

For number 1. We first need to find how much one ticket costs. To find this we divide profit by number of tickets sold. So,

13.50/15 = $0.90

So to find the cost of 21 tickets we times the cost per ticket by 21

21 x 0.90 = 18.9

So $18.90

2.

They sold 6 cases in 40 minutes.

6/40 = 0.15

They sell 0.15 cases per minute

For a we wanna see if they can sell 27 cases in 180 minutes so

0.15 x 180 = 27

So a is true

B)

0.15 x 80 = 12

So b is true

C)

0.15 x 120 = 18

C is true

D)

0.15 x 160 = 24

D is true

E)

0.15 x 200 = 30

E is false
