Question

Which is the better buy?

5-foot roll of waxed paper for $4.20
90-inch roll of waxed paper for $11.70

Answer 1

To find the better buy between two waxed paper rolls, calculate the cost per foot for each. The 5-foot roll at $0.84 per foot is a better buy than the 7.5-foot roll at $1.56 per foot.

Step-by-step explanation:

To determine which roll of waxed paper is the better buy, we need to calculate the cost per foot for each option. First, we convert the length of the rolls to the same unit of measurement. Since 1 foot equals 12 inches, a 90-inch roll is equivalent to 7.5 feet (90 inches / 12 inches per foot).

Next, we calculate the cost per foot for each roll:

• 5-foot roll at $4.20: $4.20 / 5 feet = $0.84 per foot
• 7.5-foot roll at $11.70: $11.70 / 7.5 feet = $1.56 per foot

Comparing the costs per foot, the 5-foot roll at $0.84 per foot is cheaper than the 90-inch (7.5-foot) roll at $1.56 per foot. Therefore, the 5-foot roll of waxed paper is the better buy.
