Noah's brother sells cars and earns 4.5% commission. He sold a truck for $62,000. How much commission will his brother earn?

$2790

Step-by-step explanation:

all you have to do is multiply $62,000 by 4.5% which will give you $2790

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
