Question

Peter spends $450 on groceries in 3 months.

If Peter spends the same amount every month, what is the amount he spends every month?

Answer 1

Well, if you want to know the money every 1 month and you only have the clue, $450 in 3 months, then you want to divide 450/3= 150 so he earns $150 each month! 

If you need anymore help, just ask!

Answer 2

$450 was spent for the entire 3 months.

If equal amount was spent for each month.

Amount for each month =  450 / 3  = 150

Amount spent for each month is $150.
