The employees of a hardware store ordered lunch from a local delicatessen. The lunch consisted of 4 turkey sandwiches and 7 orders of french fries, for a total cost of $23.10. The next day, the employees ordered 5 turkey sandwiches and 5 orders of french fries totaling $24.00. What does the delicatessen charge for a turkey sandwich? What is the charge for an order of french fries?

Respuesta :

Answer:

Turkey sandwich is $3.9

French fries is $1.05

Explanation:

In this question, we assume the sandwiches be X and the french fries be Y

So, there are two equations which are shown below:

4X + 7Y = $23.10

5X + 5Y = $24

To find out the X and Y value we have to equate the both equations. So, we multiplied by 5 and multiplied by 4 in equation 1 and 2

So, the updated equation would be

20X + 35Y = $115.50

20X + 20Y = $96

Now subtract it, so the value would be

5Y = $19.50

Y = $3.9

Now put this Y value in any equation

4X + 7Y = $23.10

4X + 7 × $3.9 = $23.10

4X + $27.30 = $23.10

4X = $4.20

X = $1.05
