Let x represent the amount of months she has been saving for.

20x - 60 = 280

Solve for x.

20x - 60 = 280

~Add 60 to both sides

20x - 60 + 60 = 280 + 60

~Simplify

20x = 340

~Divide 20 to both sides

20x/20 = 340/20

~Simplify

x = 17

Therefore, Melanie has saved for 17 months.

Best of Luck!
