Javier has a job installing windows. He earns a rate of $75 per day plus $8 per window installed. He also receives a stipend of
$25 for snacks. Javier knows his weekly earnings can be shown with the following expression: 75d + 8w + 25
Part A: Identify a coefficient, a variable, and a constant in this expression.
Part B: If Javier works for 5 days and installs 48 windows, how much does he earn? Show your work to receive full credit.
part C: If Javier gets an increase in his stipend and receives $40 for snacks, would the coefficient, variable, or constant in the equation change? Why?
A. a coefficient would be 75 or 8. The variables d and w as the constant is 25.
B. 75d+8w+25 75(5)+8(48)+25 375+384+25 400+384 784
Javier earns $784
C. If Javier gets an increase in his stipend and receives $40 for snacks, the constant in the equation would change because The coefficients are affected by the amount of days or windows he worked/installed while the constant before, of $25, is non-related to the work due to the fact that its used for snacks. And since his stipend for snack increases, only the constant changes.
The top angle is 90 degrees, so I would assume that m<1 is 90 degrees. Plugging this into the equation gives us 90 = 4y + 22. Subtract 22 from both sides, and we get 68 = 4y. Divide both sides by 4, and we get 17 = y.
