Question

Barry wanted to save at least $700. He opened a savings account with an initial deposit of $150. After his initial deposit, Barry then deposits the same amount of money each month for a year. If he makes no withdrawals, which inequality can be used to determine x, the number of dollars Barry deposited to his account each month?








Help!!

Answer 1

at least 700

he has already 150

he depositis the same amount for one year to attain his goal of 700

so we assume he attains his goal

150+depositintheyear is at least his goal

150+deposit≥700

deposit=deposit total in the year=

amount per month times number of months=x times 12=12x

the inequality would be 150+12x≥700
