At the state fair, 2 bags of mini donuts and 4 turkey legs cost $18.50. for $13.75, you can buy 3 bags of mini donuts and 2 turkey legs.using these amounts, which system of equations can be used to find the cost of 1 bag of mini donuts?

Respuesta :

Let’s use subtraction in this case:

Let Mini donut be D
Let turkey legs be T


(2D + 4T = 18.50)*3
(3D + 2T = 13.75)*2

6D + 12T = 55.50
-6D + 4T = 27.50

8T = 27.5
T = 3.5 The turkey leg is 3.5$


2D + 4(3.5) = 18.50

2D + 14 = 18.50


2D = 4.5
D=2.25


The cost of one mini donut would be 2.25$
