Clara bought 16 cases of water bottles. There were 12 water bottles in each case. Four students wrote and solved equations to find b, the number of bottles that Clara bought. Which student wrote and solved the equation correctly?
Answers
However,
Number of cases of water bottles= 16
Number of bottles in each case= 12
Total number of bottle = 12×16
= 192
The Student whose answer is 192 bottles is correct.
Question (Corrected):
Clara bought 16 cases of water bottles. There were 12 water bottles in each case. Four students wrote and solved equations to find b, the number of bottles that Clara bought. Which student wrote and solved the equation correctly?
A. Maya's work:
b/12 = 16
b = 1.3
B. Larissa's work:
12b = 16
b = 1.3
C. Sally's work:
b/12 = 16
b = 192
D. Anika's work:
12/b = 16
b = 192

Given:
Clara bought 16 cases of water bottles.
Each case has 12 water bottles.
To Find:
The number of bottles that Clara bought.
Define b:
Let me be the number of bottles bought
Find the number of bottles, b:
Number of bottles ÷ Number of cases = Number of bottles in each case
b ÷ 16 = 12
b/16 = 12
b = 12 x 16
b = 192
A Maya's work:
Maya's equation is correct but the calculation is incorrect
B. Larissa's work:
Larissa's equation is incorrect
C. Sally's work:
Sally's equation is correct and the calculation is also correct
D. Anika's work:
Anika's equation is incorrect.
Answer: There are 192 bottles. (C) Sally's answer is correct.
