Final answer:
The total cost of the ski jacket and ski pants is $250.
Step-by-step explanation:
To find the total cost of the ski jacket and ski pants, we first need to set up an equation based on the given information. Let's denote the cost of the ski pants as 'p'. According to the question, the ski jacket costs $20 less than twice the cost of the ski pants. So, the equation becomes: 2p - 20 = 160. To find 'p', we need to solve this equation.
First, add 20 to both sides of the equation: 2p = 160 + 20 = 180.
Next, divide both sides by 2 to solve for 'p': p = 180 / 2 = 90. So, the cost of the ski pants is $90.
Finally, to find the total cost of the ski jacket and ski pants, we add their costs together: 160 + 90 = 250. Therefore, the total cost of the ski jacket and ski pants is $250.
