Montraie is going to an amusement park. The price of admission into the park is $40, and once he is inside the park, he will have to pay $4 for every ride he rides on. How much money would Montraie have to pay in total if he goes on 11 rides? How much would he have to pay if he goes on rr rides?

Cost with 11 rides:
Cost with rr rides:

Cost with 11 rides: $40 (admission fee) + ($4 x 11 rides) = $40 + $44 = $<<40+44=84>>84

Cost with rr rides: $40 (admission fee) + ($4 x rr rides) = $40 + 4rr
