Answer:
20 months
Turn sentences into equation:
She deposits $225 every month after initial deposit of $2500 in first month
Equation: y = 2500 + (x - 1)225
where y represents total amount, x represents months
Use this equation to find at which month her account will have $6,775
2500 + (x - 1)225 = 6,775
(x - 1)225 = 6,775 - 2,500
(x - 1)225 = 4275
x - 1 = 19
x = 20
Thus, it will take 20 months when she have a total of $6,775.
