Terry earned $90 plus 10% of his sales for a net of $159. how much were his sales? $690 $820 $525 $875

First, subtract 90 from his total

159 - 90 = 69

Next, divide the remainder with 10%

Note that 10% = 0.10

69/0.10 = 690

$690 is your answer

hope this helps

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
