You want to buy a calculator that is at most 115 dollars. you already have 30 dollars saved and you make 7.50 dollars a hour. how many hours would you have to do to buy a calculator?

you need to work 12 hours to buy the calculator

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
