Answer :
Final answer:
The least and greatest amount of coffee that the machine may dispense are 7.76 ounces and 8.24 ounces, respectively, due to the 3% variance in the amount dispensed from an 8-ounce serving.
Explanation:
The student is asking about the range of liquid volume a coffee machine might dispense which varies by 3% from an 8-ounce cup. To find the least and greatest number of ounces, we must calculate 3% of 8 ounces and then subtract and add this value to 8 ounces respectively. Three percent of 8 ounces is 0.24 ounces (8 x 0.03 = 0.24). Therefore the least number of ounces is 8 ounces minus 0.24 ounces, resulting in 7.76 ounces. The greatest number is 8 ounces plus 0.24 ounces, resulting in 8.24 ounces.
