Dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate of $7.99 for shipping. Drag numbers to c
Masteriza [31]

Answer:

Shirt #1

x = 63.84 - y - z

Shirt # 2

y = 63.84 - x - z

Shirt # 3

z = 63.84 - x - y

Step-by-step explanation:

First calculate the value of the 3 shirts as follows:

$ 71.83 - $ 7.99 = $ 63.84.

$ 63.84.

The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:

x + y + z = 63.84, then for each shirt would be the following equations:

Shirt #1

x = 63.84 - y - z

Shirt # 2

y = 63.84 - x - z

Shirt # 3

z = 63.84 - x - y

For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:

<em>z = 63.84 - 20 - 30 = $ 13.84</em>
