Answer 2

Explanation:

x = number of visits

y = number of earned points

the equation for the situation is (remember the 20 points starting balance) :

y = 5.5 × x + 20

and the question is now actually after how many visits she reached 75 earned points.

therefore,

75 = 5.5 × x + 20

55 = 5.5 × x

x = 55/5.5 = 10

she gets a free movie ticket after 10 visits.
