Question

At Ice Skating Palace skates and safety equipment cost $3.50 per hour. If you have your own shoes, the safety equipment is $1.50 per hour. Your friend is selling used skates for $40, or you can rent some. Either way, you must rent safety equipment. How many hours must you skate for the cost of renting and buying to be the same?

Answer 1

The number of  hours must you skate for the cost of renting and buying to be the same is 20 hours

Let x represent the number of hours

Hence:

40+1.50x=3.50x

Subtract 1.50x from both side

2x=40

Divide both side by 2

x=40/2

x=20

Inconclu sion The number of  hours must you skate for the cost of renting and buying to be the same is 20 hours
