The cost of a 20-oz box of cereal is $4.29. A 12-oz box of the same cereal costs $3.59. Which box of cereal is a better buy?
How do you know? Provide evidence to prove your choice is correct.
You have to find out how much each cereal costs per ounce. So you must divide each price by the amount of cereal you get and compare:
$4.08/16oz=$0.255/oz
Can you find the unit price ($/oz) of the remaining 2? You will then compare. The lowest value is the best buy!
To determine which box of cereal is the better buy, we need to compare the prices per ounce.
For the 20-oz box:
Cost per ounce = Total cost / Total ounces
Cost per ounce = $4.29 / 20 oz
Cost per ounce = $0.2145/oz
For the 12-oz box:
Cost per ounce = Total cost / Total ounces
Cost per ounce = $3.59 / 12 oz
Cost per ounce = $0.2992/oz
Comparing the cost per ounce of the two boxes, we can see that the 20-oz box costs $0.2145 per ounce, while the 12-oz box costs $0.2992 per ounce.
Therefore, the 20-oz box of cereal is the better buy, as it has a lower cost per ounce than the 12-oz box.
To determine which box of cereal is a better buy, we need to compare the prices per ounce of each option. Here's how you can calculate it:
1. Take the price of the 20-oz box of cereal ($4.29) and divide it by the number of ounces (20):
$4.29 / 20 = $0.2145 per ounce
2. Next, take the price of the 12-oz box of cereal ($3.59) and divide it by the number of ounces (12):
$3.59 / 12 = $0.2992 per ounce
Now, let's compare the prices per ounce:
The 20-oz box of cereal costs $0.2145 per ounce.
The 12-oz box of cereal costs $0.2992 per ounce.
Based on these calculations, we can see that the 20-oz box of cereal is the better buy because it has a lower price per ounce. The price per ounce of the 20-oz box is $0.2145, while the price per ounce of the 12-oz box is $0.2992.
Therefore, the evidence supports that the 20-oz box of cereal is the better buy since it provides a lower cost per ounce compared to the 12-oz box.
