2 answers:
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 :
Solving this we get,
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.
Step-by-step 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
s = $6
