Answer:
He spent on fruit after 5 months is $110.
In 15 months he spent $280.
Explanation:
Fixed pay for membership is $25
And enrollment fee is $17 for each month.
The equation represents this situation is
y= 17 x + 25
He is going to stop receiving fruits once he spent $280.
Now, to find how much he spent on fruit after 5 months is plugin x as 5 into
y=17x+25 for x
y=17(5)+25
y=85+25
y=110 dollars
Now, to find how many months until $280 is to plug in y as 280 then solve the equation for x.
280 = 17 x+25
Subtract both sides 25
255 =17 x
Divide both sides by 17
x= 15 months
