Y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. After how many

Illusion [34]

To solve this problem, plugin 145 where the y is located and then solve for x
y = -27x +577
145 = -27x +577
145 -577 = -27x
-432 = -27x
-432/-27 = -27x/-27
16 = x
x = 16
After 16 weeks she will have $145 dollars in her account.
