Question

Each month, Matthew gets a $25 allowance and earns $100 mowing lawns. He uses the expression 25x + 100y to keep track of his earnings. Part A: Identify the variables and coefficients in the expression. (3 points) Part B: How many terms are in the expression, what are they, and how do you know? (4 points) Part C: Which term in the expression shows the total earned from mowing lawns? (3 points)

Answer 1

Part A
The variables would be x and y where as the coefficients would be 25 and 100

Part B
There are two terms in the expression, those being 25x and 100y. This is because s plus or minus sign separates terms, and in this case, we only have one plus sign.

Part C
The term that represents the total earnings from mowing lawns in 100y, because the prompt says that he earns $100 mowing lawns.
