Studdy Solution
STEP 1
What is this asking? Which container of mealworms costs less per ounce? Watch out! Don't just compare the prices or the weights alone; we need to compare the *unit prices*!
STEP 2
1. Calculate Adam's unit price.
2. Calculate Marco's unit price.
3. Compare the unit prices.
STEP 3
Adam bought oz of mealworms for .
To find the price *per ounce*, we'll **divide** the total price by the number of ounces.
We're doing this because we want to find out how much *one* ounce costs.
Dividing by oz gives us the price for *one* ounce.
STEP 4
\frac{\(\$8.75\)}{3.5 \text{ oz}} = \(\$2.50/\text{oz}\) So, Adam paid per ounce of mealworms.
STEP 5
Marco bought oz of mealworms for .
Just like we did for Adam, we'll **divide** the total price by the number of ounces to find the price per ounce.
Dividing by oz will tell us how much *one* ounce costs for Marco.
STEP 6
\frac{\(\$9.75\)}{3.75 \text{ oz}} = \(\$2.60/\text{oz}\) Marco paid per ounce.
STEP 7
Now, let's see who got the better deal!
Adam paid per ounce, and Marco paid per ounce.
STEP 8
Since is less than , Adam got the better deal!
STEP 9
Adam's container is the better deal, costing him per ounce compared to Marco's per ounce.
