Suppose you earned 7t-1 dollars on Monday and 8t+5 dollars on tuesday. What were your total earnings? Simplify your answer
To find the total earnings, we need to add the earnings from Monday and Tuesday:
Total earnings = Monday earnings + Tuesday earnings
Total earnings = (7t-1) + (8t+5) (substitute the given values)
Total earnings = 7t + 8t - 1 + 5 (combine like terms)
Total earnings = 15t + 4 (simplify)
Therefore, your total earnings were 15t + 4 dollars.
