Deanna is a dog groomer. On Monday, she groomed 12 dogs in 8 hours. On Tuesday, she groomed 9 dogs in 6 hours. On Wednesday, she groomed 6 dogs in 6 hours. Which statements are true about Deanna’s workload? Check all that apply.
Answer
A
The Wednesday ratio was equal to the Monday ratio.
B
The Monday ratio was equal to the Tuesday ratio.
C
The Tuesday ratio was greater than the Wednesday ratio.
D
The Wednesday ratio was less than the Monday ratio.
E
The Monday ratio was twice the Wednesday ratio.
Explanation
Compare dogs groomed per hour: Monday was 12 ÷ 8 = 1.5 dogs per hour, Tuesday was 9 ÷ 6 = 1.5, and Wednesday was 6 ÷ 6 = 1. B is true because Monday and Tuesday had equal rates. C and D are true because Tuesday’s rate was greater than Wednesday’s, and Wednesday’s rate was less than Monday’s. Monday’s rate was not twice Wednesday’s, so E is false.
