Which is the better deal: 8 ounces of shampoo for $0.89 or 12 ounces of $1.47?
Can someone please explain to me how to do this problem.
0.89 / 8 = $0.11 per ounce
1.47 / 12 = $0.12 per ounce
0.89 / 8 = $0.11 per ounce
1.47 / 12 = $0.12 per ounce
To determine which deal is better, you need to compare the price per ounce for each option. Here's how to do it:
1. Calculate the price per ounce for the first deal (8 ounces of shampoo for $0.89):
Divide the total cost ($0.89) by the number of ounces (8):
$0.89 ÷ 8 = $0.111 per ounce
2. Calculate the price per ounce for the second deal (12 ounces of shampoo for $1.47):
Divide the total cost ($1.47) by the number of ounces (12):
$1.47 ÷ 12 = $0.1225 per ounce
3. Compare the price per ounce for both deals:
The first deal has a price of $0.111 per ounce, while the second deal has a price of $0.1225 per ounce.
4. Determine which deal offers a lower price per ounce:
Since $0.111 is less than $0.1225, the first deal (8 ounces of shampoo for $0.89) is the better deal. It offers a lower price per ounce compared to the second deal.
Therefore, the better deal is 8 ounces of shampoo for $0.89.
