Need to do it the equation and the real world problem

A volleyball uniform costs $13 for the shirt, $11 for pants, and $8 for socks. Write two equivalent expressions for the total cost of 12 uniforms. Then find the cost.  

Write an expression for the cost of 1 uniform, add $13, $11 and $8 .

$13+$11+$8

Write an expression for the cost of 12 uniforms, multiply 12 by the cost of 1 uniform.

12($13+$11+$8)

Simplify using the distributive property.

=12⋅13+12⋅11+12⋅8=156+132+96

Now Add.

=384

So, the total cost of 12 uniforms is $384 .

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

it is true
