Subash is saving to buy a video game that costs $72. He earns $12 per week for doing the dishes and spends $3 on ice-cream. Which equation can be used to find how many weeks it will take him to save enough money for the video game?

Correct answer is 'A'

Step-by-step explanation:

so money he save per week = $12 - $3 = $9

Now,

To earn 9$ it takes one week or it can be represented as:

$9 = 1 week

So,

$1 = 1/9 week

$72 = (1/9*$72)weeks

$72 = 8 weeks

therefore it will take 8 weeks to save enough money for the video game

do you have the measurements?
