Question

Jordan saved four fifths of the amount he needs to buy an $80 video game if he earns $7.75 per hour by working at the pizza shop how many hours does he need to work to save the rest of the money for the video game round to the nearest hour

Answer 1

1/5 of 80 =16
16x4=64
this means he needs 16 more dollars
16/7.75=2.06451612903
this means that he has to work for two more hours.

hope this helps :)
