the kayak costs 440.
she has saved 160 so far.
she plans on saving 40 each month.

equation is 440 = 160 + 40 * x

x represents the number of months.
to solve for x, do the following:
start with 440 = 160 + 40 * x
subtract 160 from both sides of the equation to get:
280 = 40 * x
solve for x to get:
x = 280 / 40 = 7
she will have enough money to pay for the kayak in 7 months.
