b) $0.17
c) $1.65
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
