Question

Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. If Laura returned the movie and paid $5.00, how many nights did she keep the movie?

Answer 1

let x be the additional night

2 + 0.5 x = 5

solve for x

note: to find the answer you need to add 1. because x is just the additional nights. the problem is the total nights so you add the 1 night for the flat fee
