Suppose you earned 9t-2 dollars on Monday and 5t+7 dollars on Tuesday. What were your total earnings? Simplify your answer.

Answer 1

To find the total earnings, we add the earnings from Monday and Tuesday:
total earnings = 9t-2 + 5t+7
Simplifying by combining like terms, we get:
total earnings = (9t + 5t) + (-2 + 7)
total earnings = 14t + 5
Therefore, the total earnings were 14t + 5 dollars.
