Final answer:
The original cost of the shirt was $105 and the original cost of the shoes was $140. Adding them together, the total original cost of the shirt and shoes before the sale was $245.
Step-by-step explanation:
To solve this problem, we simply need to calculate the original prices before the sales discount and then sum them up for both the shirt and the shoes.
For the shirt:
Original price of shirt = Sale price of shirt × 3
= $35 × 3
= $105.
For the shoes:
Original price of shoes = Sale price of shoes × 5
= $28 × 5
= $140.
Now, we add both original prices together to find the total cost before the sale:
Total original cost = Original price of shirt + Original price of shoes
= $105 + $140
= $245.
