Equation:
Y=10+3x
Because Y can not equal more than 55
55>10+3x
-10
45>3x
45/3 equals 15 so 15 is the maximum number of months Joyce will remain in the club.

Here's the equation:
y=3x+10
y=55 cd's only from that club
55=3x+10
3x=45
x=15
She needs to stay on that club for 15 months or one year and three months.

since she already received 10 that leaves 45 to go so therefore ,3 per month ,equal 15 months to go

(55-10)/3 = x
x = 45/3
x=15

y = 10 + 3x
55 >= 10 + 3x
45 >= 3x
15 >= x, so x = 5, no fuss about fractions of a month.
