Suppose you earned 9t-2 dollars on Monday and 5t+7 dollars on Tuesday. What were your total earnings? Simplify your answer.
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.
To find your total earnings, you need to add the amounts earned on Monday and Tuesday.
The amount earned on Monday is represented by 9t-2 dollars.
The amount earned on Tuesday is represented by 5t+7 dollars.
So, the total earnings can be found by adding these two amounts:
Total earnings = (9t-2) + (5t+7).
To simplify this expression, you can combine like terms:
Total earnings = 9t + 5t - 2 + 7.
Combining like terms, we get:
Total earnings = 14t + 5.
So, your total earnings are 14t + 5 dollars.
