One slice of pizza cost $1.50. Cindy sold a total of 87 pizzas and drinks, she wants to know how many she sold separately.
I want to sell enough pizza and drinks to get to $78.50 to go out with my friends.
1.Variables= X=pizza Y=drinks 2. 1.50x+0.50y=78.50 X+Y=87 3. Rewrite your equation -X+Y=78---> Y= -X+87 4. Plug in Y 1.5x+0.5(-x+87)=78.5 5.Distribute 1.5x+(-0.5x)+43.5=78.5 combine like terms x+43.5 solve for X x+43.5 -43.5=78.5 -43.5 X=35 Plug in X Y=-x+87 y=-35+87 Y=52
I need to get to the mall before my friends leave me!!
CHECK: solution-(35,52) 1.5(35)+0.5(52)=78.5 Cindy sold 35 pizzas and 52 drinks.
OMG Cindy finally we were about you!!?
I made enough money to come to the mall and meet my friends!!!
