I need help on JUST number 13. I am begging you please, please help me.

C. 6%

Step-by-step explanation:

You have to multiply 36 by A,B,C,D. Then add that number to 36.

First multiply all the options by the original price ($36)

A. 2.16% = 36 x 2.16% = 0.7776this answer plus our original answer isn’t 38.16

B. 9.4% = 36 x 9.4% = 3.384This answer plus 36 doesn’t equal 38.16

C. 6% = 36 x 6% = 2.162.16 plus 36 equals 38.16

D. 8% = 36 x 8% = 2.88doesn’t equal 38.16 when added to 36.

Therefore 6% or C is the correct answer.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
