Respuesta :

Answer:

The cost of a shirt is $21.99 and of a tie is $14.99.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of a shirt.

y is the cost of a tie.

Jordan buys 3 identical shirts and 2 identical ties for $95.95.

This means that [tex]3x + 2y = 95.95[/tex]

Gabe buys 4 of the same shirts and a tie for $102.95.

This means that [tex]4x + y = 102.95[/tex]

So

[tex]y = 102.95 - 4x[/tex]

Replacing in the first equation:

[tex]3x + 2(102.95 - 4x) = 95.95[/tex]

[tex]3x + 205.9 - 8x = 95.95[/tex]

[tex]5x = 109.95[/tex]

[tex]x = \frac{109.95}{5}[/tex]

[tex]x = 21.99[/tex]

[tex]y = 102.95 - 4x = 102.95 - 4*21.99 = 14.99[/tex]

The cost of a shirt is $21.99 and of a tie is $14.99.
