Question

An ice skating rink charges $5 for admission and $2.50 to rent skates. Jill can purchase a new pair of skates for $65. How many times would she need to go the rink to justify buying the skates rather than renting a pair?

Answer 1

i think you should find the lowest common multiple

Answer 2

You may put an equation too.

Answer 3

the answer is one of these three

Answer 4

5 units
10 units
12.5 units

Answer 5

5 for admission is the money necessary.
2.50 for every skate.

So if you rent x skates, you'd have the rent given by \(5 + 2.5x\)

Answer 6

Equate that with 65 and solve for \(x\). \[ \color{Black}{\Rightarrow 5 + 2.5 x = 65}\]\[ \color{Black}{\Rightarrow 2.5x = 65 - 5 }\]\[ \color{Black}{\Rightarrow x = {65 - 5 \over 2.5} }\]Got it?
