Product of 8 and the sum of 4 and a number:

sum of 4 and a number: (4 + n)

Product of 8

8 x (4 + n) is 112

8 x (4 + n) = 112

Distribute

32 + 8n = 112

Subtratc

8n = 80

Divide by 8

n = 10

The number is 10, and next time please put options because it says "Which equation could be used to solve for the number?"
You probably are supposed to use PEMDAS (the order of operations) to represent this equation so i would choose C.

It sounds like 8*(n+4)=112 then you have simple algebraic equation that could be solved by a TI-Calculator or by hand
Divide both sides by 8
Subtract four from both sides
You're left with n= the answer
