Answer:
Step-by-step explanation:
60x^2+261x+162
you have to subtract 14 to the total cost to see how much you get back, use a calculator next time.
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,
=512-8
=504
Hope this helps!
