3 movie tickets cost $36. At this rate, what is the cost per ticket? 3 ice cream cones cost $.25. At this rate, how much do 2 ice cream cones cost? 3 bananas cost $0.99. At this rate, how much do 5 bananas cost?

a) $12

b) $0.17

c) $1.65

Step-by-step explanation:

a) 3 movie tickets cost $36. At this rate, what is the cost per ticket?

3 movie tickets = $36

1 ticket = x

Cross Multiply

3x = $36

x = $36/3

x = $12

Therefore, the cost per ticket = $12

b) 3 ice cream cones cost $.25. At this rate, how much do 2 ice cream cones cost?

3 ice cream cones = $0.25

2 ice cream cones = x

Cross Multiply

3x = 2 × $0.25

3x = $0.50

x = $0.50/3

x = $0.1666666667

Approximately = $0.17

Therefore, the cost of 2 ice cream cones = $0.17

c) 3 bananas cost $0.99. At this rate, how much do 5 bananas cost?

3 bananas = $0.99

5 bananas = x

Cross Multiply

3x = 5 × $0.99

x = 5 × $0.99/3

x = $1.65

Therefore, the cost of 5 bananas = $1.65

x/3-10=8

x/3=18

x=48
