Mrs. Diaz wishes to save at least $1500 in 12 months. If she save $300 during the first 4 months, what is the least possible average amount that she must save in each of the remaining 8 months?
After 4 months, 4 x 300 = $1200 will be saved. That leaves $300 to go in 8 months. What would that be per month, in equal payments?
