Question

Q: Jaxon has $65 in his savings account. He deposits $15 every week. His father also deposits $25 into the account every time Jaxon mows the lawn. His savings account balance can be shown with the following expression:

65 + 15w + 25m

Part A: Identify a coefficient, a variable, and a constant in this expression.

Part B: If Jaxon saves for 20 weeks and mows the lawn 3 times, how much will he have in his account?

Part C: If Jaxon had $75 in his savings account, would the coefficient, variable, or constant in the expression change?

Answer 1

Constant: 65
Coefficient: both 15 and 25 are coefficients
Constant: both w and m are constants

65 + 15(20) + 25(3) = 440

The constant would change from 65 to 75
