Answer:
14 visits
Explanation:
According to the scenario, calculation of the given data are as follows,
Signup rewards = 50 points
Each visit reward = 10.5
Total points needed = 190
Let, number of visits = x
So, we can calculate number of visits by using following formula,
50 + (10.5 × X) = 190
10.5X = 190 - 50
10.5X = 140
X = 140 ÷ 10.5
X = 13.33 or 14 visits.
Hence, she needs to make 14 visits in order to earn a free movie ticket.
