Final answer:
Jacoby makes $3.75 for every gallon of orange juice sold, derived by dividing the total earnings of $15 by the total gallons sold (4). However, this exact answer is not an option provided, suggesting an error in the question or answer choices.
Step-by-step explanation:
The rate at which Jacoby earns money selling his orange juice can be found by determining how much he earns per gallon. According to the information, Jacoby makes $15 for every 4 gallons sold. To find this rate, we need to divide the total dollars earned by the total gallons sold.
Total dollars earned = $15
Total gallons sold = 4 gallons
To calculate the rate per gallon, we use the formula:
Rate = Total dollars earned ÷ Total gallons sold
Substitute the values into the formula:
Rate = $15 ÷ 4 gallons
Rate = $3.75 per gallon
This means that for every gallon of orange juice sold, Jacoby earns $3.75. However, among the given options, there is no option that exactly matches $3.75 per gallon, which indicates that there may be a typo or mistake in the question or the options provided. If the question intended to ask for the closest approximate rate, then $4 for every gallon sold would be the closest to the calculated rate, but with the exact values given, none of the options are correct.
