Ms. Davis hires Kyle to mow the grass, edge the lawn, clean up the leaves, and plant 2 flower beds. Kyle spends 3.2 hours completing the work. What is Kyle's average hourly earnings for the job?
Responses
A $15.00$15.00
B $16.25$16.25
C $17.50$17.50
D $18.75$18.75
E $20.25
In order to find Kyle's average hourly earnings for the job, we need to divide the total amount he earned by the number of hours he worked.
Let's assign a variable to Kyle's average hourly earnings, such as "x".
We know that Kyle spent 3.2 hours completing the work, so we'll multiply his average hourly earnings by 3.2 to find the total amount he earned for the job.
3.2x = total income from the job
From the given responses, we need to find the value of "x" that will make the equation true.
Let's examine the provided options:
A) $15 * 3.2 = $48
B) $16.25 * 3.2 = $52
C) $17.50 * 3.2 = $56
D) $18.75 * 3.2 = $60
E) $20.25 * 3.2 = $64.80
Since option B yields the closest value to 3.2x, we can conclude that Kyle's average hourly earnings for the job are $16.25.
Therefore, the correct response is B) $16.25.

Henry did 5/6
of his math problems. The next day, he checked 2/3
of the homework problems he did the night before. What fraction of the homework problems did he check?
Responses
To find out what fraction of the homework problems Henry checked, we need to multiply the fractions 5/6 and 2/3:
(5/6) * (2/3) = 10/18
The fraction 10/18 is already simplified, but we can simplify it further by dividing both the numerator and denominator by their greatest common divisor, which is 2:
10/18 = (10 ÷ 2) / (18 ÷ 2) = 5/9
Therefore, Henry checked 5/9 of the homework problems.
The correct response is 5/9.
