Answer:
14 visits
Step-by-step 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.
Answer:
-36 ÷ -3
Step-by-step explanation:
Change in her school lunch account balance per lunch = -3
Total change in her school lunch balance last month = -36
Expression to show number of times Elena bought lunch last month = Total change in her school lunch balance last month ÷ Change in her school lunch account balance per lunch
= -36 ÷ -3
= -36/-3
= 12 times
Elena bought lunch 12 times last month
The answer is b. If you solve for x you get -3 and then do 138-3
