Pete earned $8 an hour baby-sitting, and $10 an hour mowing the lawn. He baby-sat for 3 hours and mowed for 2 hours. How much more money does he need to buy a computer game that costs $45?

Respuesta :

$8 X 3 hours = $24
$10 X 2 hours = $20

he has made $44 total  he needs $1 to get the computer game
First, you would need to create an equation to determine how much money he has earned thus far. 
($8 × 3) + ($10 × 2) 

Then, solve it. 
($8 × 3) + ($10 × 2) 
$24 + $20 = $44

Now, all you would need to do is subtract the money he has made so far from the money he needs. 
$45 - $44 = $1

Pete needs $1 more to buy a computer game. 

I hope this helps!
