Sual would like to buy a new pair of stake for $115. So far he has saved $40. if he earns 7.50$ pre hour, how many hours must he work until he can buy the skates?
Answer provided by our tutors
let 'x' be the hours he needs to work to buy the skates
in 1 hour he makes $7.50
in x hours he will make $7.50x
40 + 7.50x = 115
x = 10 hours
Sual has to work 10 hours.
