Mr. diaz wishes to save at least $1500 in 12 months. if he saves 300 during the first 4 months what is the least possible average amount that she must save in each of the remaining 8 months

If she saved $300 the first 4 months then she needs to save another $1200 in the next 8 months, right? So now we divide 1200 by 8 to get 150. So each month for the next 8 months she needs to save $150 to reach the goal. Make sense?

A. is the answer in this question
