Question

NEED HELP PLEASE!!!

Allen's team was also required to buy two pairs of uniform pants and two baseball caps, which total $68. A pair of pants cost $12 more than a baseball cap.

Answer 1

Variables:
p = uniform pants
c = baseball caps

Equations:

`2p + 2c = 68`

`p - c = 12`
****************************************************************************************
Step 1.

`\left {{2p+2c=68} \atop {p-c=12}} \right`

Step 2.

`\left {{2p+2c=68} \atop {2(p-c=12)}} \right.`

Step 3.

`\left {{2p+2c=68} \atop {2p-2c=24}} \right.`

Step 4.

`4p = 92`

Step 5.

`(4p)/(4) = (92)/(4)`

`p=23`

Step 6.

`p-c=12`

`23 - c=12`

`23=12+c`

`11=c`

Baseball Pants = $23
Baseball Caps = $11
