Answer :
Final answer:
Leah's cup holds 40% less than Juan's 64-ounce cup, so we calculate 40% of 64 ounces (25.6 ounces) and subtract it from 64 ounces to find Leah's cup capacity: 38.4 ounces. Thus, the correct answer is (A) 38.4 ounces.
Explanation:
Juan has a cup that holds 64 ounces. Leah's cup holds 40% less than this amount. To find out how many ounces Leah's cup will hold, we first need to calculate 40% of 64 ounces.
40% can be expressed as 0.40 in decimal form. Therefore, we multiply 64 ounces by 0.40 to find the quantity that Leah's cup holds less than Juan's. This results in 25.6 ounces. We then subtract this amount from the original 64 ounces to find the capacity of Leah's cup.
64 ounces - 25.6 ounces = 38.4 ounces. This means that Leah's cup will hold 38.4 ounces, which makes option (A) the correct answer.
The unit of measure to consider for this calculation is that 1 cup is equivalent to 8 fluid ounces. However, since we are dealing with larger quantities in this scenario, this unit of measure is more of a reference to understand how units of capacity are related. The actual calculation doesn't require conversion between cups and ounces, as we already have the capacity in ounces.
