Answer 1

two pizzas and a salad cost $29.00. Three pizzas and 2 salads cost $46.00. How much is a pizza? How much is a salad?

Write the system of equations that would be used to solve this problem.
Let x = price of a pizza
y= price of a salad
2x +y=29.00
3x+2y=46.00


Solve the system of equations in problem #5.
-4x-2y =-58.00 (Multiply the first equaton by -2.)
3x +2y =46.00
----------------------------------
-x =-12
x=12.00 price of a pizza.
From this equation:
2x+y=29.00
2(12)+ y=29.00
24+y=29.00
y=29=24
y=5
