Question

Keith has a debt of $150 at the beginning of the summer he wants to have at least $200 in the account at the end of the summer if he plans to save $75 each week what is the minimum number of weeks he'll have to work in order to meet his goal? Please help and show how to solve it and tell me a number line

Answer 1

the difference between 200 and -150 is 350. 350÷75= 4.666666... but as it is whole weeks it will be 5 weeks
