I will do a and b and you do the rest.
For (a), the equation is x + y = 154.
For (b), the equation is 320x + 85y = 14,970.
We have two equations in two unknowns.
Use the substitute method to find x and y (the given c). Once you have x and y, use that to find d.
Take it from here.
3s = 72 (Multiply 8 both side).
s = 24 (divide by 3 both side)
