John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.

Answer:
40 and 16
Step-by-step explanation:
Let's say these numbers are 5x and 2x.
Their sum is 56, so
5x + 2x = 56
7x = 56
x = 8
Now substitute the unknown value with 8.
5 · 8 = <u>40</u>,
2 · 8 = <u>16</u>

<u>The Perimeter of a Shape</u>
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm
