Suppose you earned 8t-3 dollars on Monday and 6t + 5
dollars on Tuesday. What were your total earnings? Simplify
your answer.
A) 21+2
B) 21-8
C) 14t+2
D) 14t-8
The total earnings would be the sum of earnings from Monday and earnings from Tuesday:
(8t-3) + (6t+5)
Simplifying by combining like terms:
14t + 2
Therefore, the answer is C) 14t+2.
To find your total earnings, you need to add the earnings from Monday and Tuesday.
Earnings on Monday: 8t - 3 dollars
Earnings on Tuesday: 6t + 5 dollars
To add the two expressions, you combine like terms:
(8t - 3) + (6t + 5)
Now, distribute the plus sign to both terms inside parentheses:
8t + 6t - 3 + 5
Combine like terms:
14t + 2
So, your total earnings can be simplified to 14t + 2 dollars.
Therefore, the answer is C) 14t + 2.
