1.Mario purchased 15 tickets to a football game for $13.50. How much would it cost to purchase 21 tickets? $ 2.Student Council sells bottled water at the cheerleading competition as shown below. Determine of each statement is true or false.

Cases sold: 3 6
Time (min): 20 40

a) They sell 27 cases in 3 hours
b) They sell 12 cases in 1 hr 20 minutes
c) They sell 18 cases in 2 hours
d) They sell 24 cases in 2 hrs 40 minutes
e) They sell 36 cases in 3 hrs 20 minutes

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
