Question

jordan saved 4/5 of the amount he needs to buy 80 video game .if he earns 7.75 per hour by working at a pizza shop ,how many hours does he need to work to save.the resy for the money for the video game

Answer 1

First you need to know how much 1/5 of the game is.

1/5×80=
80/5=
16

Now find out how much he has saved up (4/5).

16×4=
64

Now find how much more he needs to collect.

80-64=
16

Now find how many hours he needs to work to be able to collect 16 or more dollars (in order to buy the video game).

7.75x≥16
÷7.75

The value of x (hours worked) has to be 3 or greater.

Unless you want to tell the teacher that Jordan should work 2.064516129 hours.

------------------

He has to work 3 hours even though he earns more than the necessary amount in order to buy the game because if he only worked 2 hours he wouldn't have ENOUGH money.
