Suppose you earned 7t + 3 dollars on Monday and 11t - 6 dollars on Tuesday. What were your total earnings? Simplify your answer.

Question

A) 18t + 9
B) 18t - 3
C) -4t - 3
D) -4t + 9

Answer 1

Total earnings = 7t + 3 + 11t - 6
Total earnings = (7t + 11t) + (3 - 6)
Total earnings = 18t - 3

Therefore, the answer is B) 18t - 3.
