Answer:
The large size gives the lowest price per ounce of 3.11875, therefor the best in terms of price
Explanation:
Step 1: Determine expression for price per ounce
The expression for the total price of an ice cream dessert is as follows;
T=p×n
where;
T=total price of ice cream
p=price per ounce of ice cream
n=number of ounces of ice cream
Step 2: Convert total price to price per ounce
The expression can be rewritten as;
p=T/n
1. For small 6 ounce at $2.49, T=2.49, n=6-oz
p=2.49/6=0.415
The price per ounce of the small ice cream dessert=$0.415 per ounce
2. For the Medium 10-oz for $3.49, T=$3.49, n=10-oz
p=3.49/10=0.349
The price per ounce of the medium ice cream dessert=$0.349 per ounce
3. For the Large 16-oz for $4.99, T= $4.99, n=16
p=4.99/16=$0.311875
The price per ounce of the medium ice cream dessert=$0.311875 per ounce
4. For the super size 24-oz for $7.69, T=$7.69, n=24
p=7.69/24=0.32
The price per ounce of the super size cup is 0.32 per ounce
The large size gives the lowest price per ounce of 3.11875, therefor the best in terms of price
