Lets plug in the answer choices and see which one works
A. x = -6
| -6 | < 3
6 < 3
False, so A is not the answer
B. x = -5
| -5 | < 3
5 < 3
False, so B isn't the answer
C. x = -1
| -1 | < 3
1 < 3
True, so C is the answer.
But lets just check D to make sure C is the answer.
D. x = 2
| 2 | < 3
2 < 3
False, so D isn't the answer either.
C is your answer :)
Part A : The coefficients in the expression are "8" and "15. The variables in the expression are "h" and "t".
Part B: There are actually two terms in the expression and they are "8h" and "15t". Terms are separated by a plus sign or a minus sign.
Part C: "15t" is the term in the expression that shows the total earned for tablets sold.
