Final answer:
To determine the total cost for Ms. Gill's banners, we multiply the length of each banner by the per-yard price and add the costs together. Two banners at 178 yards and one at 258 yards, all at $28 per yard, are calculated for a final total cost.
Step-by-step explanation:
The question asks us to calculate the total amount Ms. Gill would pay for her custom-made banners at a rate of $28 per yard. She orders two banners, each 178 yards long, and one banner that is 258 yards long.
We first calculate the cost of the two banners that are 178 yards long:
- Cost of one 178-yard banner = 178 yards × $28 per yard.
- Total cost for two 178-yard banners = 2 × (178 yards × $28 per yard).
Next, we calculate the cost of the one 258-yard banner:
- Cost of one 258-yard banner = 258 yards × $28 per yard.
Lastly, we add the cost of all three banners to find the total cost:
- Total cost = Cost of two 178-yard banners + Cost of one 258-yard banner.
