Answer:
The original cost of the skis is: $150
Step-by-step explanation:
- The question tells us that Mr. MacGill buys a pair of skis at 1/3 of the price. We are also told that he uses a gift card of $40 after which the cost of before taxes was $10.
- We are asked to find the original price of the skis.
- If the original cost of the skis is X. Then a third of the price of the skis is given by:
[tex]\frac{X}{3}[/tex]
- This value is now the total amount he paid and he used the 40 gift card, which reduced the cost before taxes to $10, that was in turn paid for him to purchase the item.
Thus, we can say:
[tex]\frac{X}{3} =40+10[/tex]
[tex]\frac{X}{3} =50[/tex]
Cross multiply
[tex]X=50~x~3=150[/tex]
Final Answer
The original cost of the skis is: $150
