Is this correct 3 1/8 • 4 = 28/8 • 4/1 = 100/8 divided by 4 = 25/2 = 12 1/2

It is incorrect because 3 1/8 times 4 is 12 1/2

28/8 or 3 1/2 times 4/1 or 4 is 12 1/2

100/8 divided by 4 is 3 1/8, and is not 12 1/2

the answer is 8

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
