i need to know how to turn this into a expression

Question

The cost for bowling is $5 per player for shoe rentals and $45 per hour to book a lane. Suppose a group of f friends go bowling for h hours. Write an expression for the total cost for the group of friends to go bowling.

Answer 1

Information given

Cost of shoe rental per person = $5

Cost to book a lane for one hour = $ 45

Find

Cost of shoe rental for f players = 5x f = 5f

Assume 5 max players can be assigned to one lane.

so, one player gets 1/5 th of the lane

f players would get f x 1/5 = f/5 of a lane for one hour.

The cost to book f/5 th of a lane for one hour would be f/5 x 45 =9f

The cost to book f/5 th of a lane for h hours would be 9f x h = 9fh

Therefore, the expression for the total cost for bowling for f players for h hours = 5f + 9fh

Answer 2

Total = shoes + lane

Total = 5f +45h
