Let the price of 1 shirt be represented by = s

A pair of pants costs twice as much as a shirt, then the cost of pants is = 2s

The total cost of 1 pair of pants and 1 shirt is $18 , means :
s+2s=18

Solving this we get,


3s=18


s=6

So, the price of 1 shirt is $6 and price of 1 pair of pants is = 2s = 2*6 = $12.

Answer:

s + 2s = 18, will be the equation.

Explanation:

Let 's' represents the cost of 1 shirt.

As per given statement in the question "a pair of pants costs twice as much as a shirt".

The cost of a pair of pants = $2s

The total cost of 1 pair of pants and 1 shirt = $18

so the equation to find the cost of 1 shirt will be

s + 2s = 18

3s = 18


(3s)/(3)=(18)/(3)

s = $6
