Final answer:
To calculate the unit rate of juice per fluid ounce, convert two gallons to fluid ounces using the equivalence of 1 gallon = 4 quarts and 1 quart = 32 fluid ounces, then divide the total cost by the number of fluid ounces. The unit rate is $0.20 per fluid ounce.
Step-by-step explanation:
Unit Rate Calculation
To calculate the unit rate of the juice Angel bought per fluid ounce, we first need to determine how many fluid ounces are in two gallons. We will use the following unit equivalences to perform the conversion:
- 1 gallon = 4 quarts
- 1 quart = 32 fluid ounces
Since there are 4 quarts in a gallon, we will first multiply the number of gallons by 4 to find out how many quarts there are in two gallons:
2 gallons × 4 = 8 quarts
Next, since there are 32 fluid ounces in a quart, we will multiply the number of quarts by 32 to get the total number of fluid ounces:
8 quarts × 32 fluid ounces/quart = 256 fluid ounces
Now that we know there are 256 fluid ounces in two gallons, we can calculate the unit rate by dividing the total cost by the total number of fluid ounces:
$51.20 ÷ 256 fluid ounces = $0.20 per fluid ounce
Therefore, the unit rate for the juice is $0.20 per fluid ounce.
