C: If Javier gets an increase in his stipend, and received $40.00 for snacks, the constant in the equation would change. The Co-efficient are affected by the amount of days, or windows he worked. installed, while the constant before, of $25.00 is non related to the work due to the fact that it's used for snacks. So, since his stipend increased for snacks, the only thing changes was the constant.
Part A: 75 and 8 are both coefficients in this case since both numbers are in front of a variable. D and W are two variables in this expression since they are letters that represent unknown numbers. 25 is the constant since that number does not change.
Part B: If Javier works for 5 days and installs 48 windows, he earns $784. 75d+8w+25 75(5)+8(48)+25 375+384+25 784
Part C: If Javier receives $40 for snacks instead of 25, the constant would change since 25 was the constant to begin with. The rest of the expression would stay the same. The new expression would look like this: 75d+8w+40.
