It costs $4 to enter the fair. Each ride costs $2.50 You have $21.50. How many rides can you go on?

Answer 1

Genesis Allen

You can go on #7# rides.

Total amount of money available #= $21.50#

The cost to enter the fair #= $4#

The amount of money remaining after paying to enter the fair #= $21.50 - $4 = $17.50#

The cost for each ride #= $2.50#

The individual is limited to the same number of rides.

#("Total amount of money available" ("After entry fee payment"))/("Cost of each ride")#

#= ($17.50)/($2.50) #

#= 7#
