Darren wins a coupon for $4 off the lunch special for each of 5 days. he pays $75 for his 5 lunch specials. write and solve an equation to find the original price (p) for one lunch special.

rick would give her the best deal as he will charge $8.88 per hour

both equations and proportions are better.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
