To find the better deal, we need to calculate the unit rates for each vendor.
For the online vendor, Cheyenne can buy 7 rolls of ribbon for $3.57. Thus, the unit rate is:
$3.57 / 7 rolls = $0.51/roll
For the craft store, Cheyenne can buy 18 rolls of ribbon for $9.36. Thus, the unit rate is:
$9.36 / 18 rolls ≈ $0.52/roll
To determine how much is saved per roll by purchasing ribbon at the vendor with the better deal, we compare the unit rates. Since the unit rate at the online vendor is $0.51/roll and at the craft store is $0.52/roll, Cheyenne would save:
$0.52/roll - $0.51/roll = $0.01/roll
Therefore, Cheyenne would save $0.01 per roll by purchasing the ribbon at the online vendor, making it the better deal.
