2.) Bill sells cleaning products on commission. He earns 40% commission on his sales. If he has sales of $983, how much commission does he earn?

$393.20

Step-by-step explanation:

There are two easy ways to solve this:

1) Use a setup and cross multiply.

First, set up your problem.

$ x    =  40%

$983    100%

$983 is the total amount, so it is equal to 100%. We're trying to find 40% of it, so we can label the amount as $x. Remember, each side has to be in the same type of measurements (i.e. dollars, percentages, inches, etc.).

Then, cross multiply. You should end up with:

100x = 39,320

Then, simplify.

x = 393.2

x = $393.20

2) Convert the percentage to a decimal and multiply.

First, convert the percentage you're looking for into a decimal:

40% × 100 = 0.4

Then, multiply the decimal with the total sales amount:

$983 × 0.4 = 393.2

                   = $393.20

answer: i think it's a

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
