Yesterday, Sarah spent 35 1/2
minutes studying for a test. Emma spent 1 1/2
times that amount studying for a different test. How many minutes did Emma spend studying?
Sarah = 35 1/2 minutes
Emma = 1 1/2 * 35 1/2 minutes
Emma = 3/2 * 71/2
Emma = 213/2
Emma = <<213/2=106.5>>106.5 minutes
Emma spent 106.5 minutes studying. Answer: \boxed{106.5}.

Sarah = 35 1/2 minutes
Emma = 1 1/2 * 35 1/2 minutes
First, let's convert 35 1/2 to a mixed number:
35 1/2 = 70/2 + 1/2 = 71/2
Now, let's calculate Emma's studying time:
Emma = 1 1/2 * 71/2
Emma = 3/2 * 71/2
Emma = 3/2 * 71/2
Emma = 213/2
Emma spent 213/2 minutes studying.
To express it as a mixed number, we divide 213 by 2:
213 ÷ 2 = 106 with a remainder of 1
So, Emma spent 106 and 1/2 minutes studying. Answer: \boxed{106\frac{1}{2}}.
your supposed to pick one of the answer choices given
I apologize for the confusion. In this case, the answer choice that matches the calculation is "106 1/2 minutes" or "106 and 1 half minutes".

Since the provided information mentions a chart with flat fees for the services, and the hourly earnings for the job are not specified, we cannot determine the exact hourly earnings for Nick's job. Therefore, none of the given responses can be considered correct without the necessary information from the chart.

Apologies for the confusion in the previous response. Let's address the questions correctly now.
Question 17: Since the hourly earnings for the job are not provided in the given responses or the question, we cannot determine the exact hourly earnings without additional information. Therefore, none of the given responses can be considered correct.
Question 18: If Devon made total payments of $936 over 8 months, and the service is the same amount each month, the change in Devon's account each month after paying for the service would be -$117. This means Devon's account balance decreases by $117 each month after paying for the service.
So, the correct answer for Question 18 is -$117.
