Final answer:
The question seems to require calculating the total number of milkshakes sold if 48 vanilla milkshakes make up 40% of the total. By dividing the number of vanilla milkshakes by the percentage they represent and then multiplying by 100, we find that the shop sold 120 milkshakes in total.
Step-by-step explanation:
The question implies that there's a need to calculate a percentage based on the provided information. Since the complete information regarding the 40% is missing, we can assume that the student meant to state that the 48 vanilla milkshakes sold represented 40% of the total milkshake sales. To find the total number of milkshakes sold, we use the formula:
Total milkshakes sold = (Number of milkshakes of a kind / Percentage that represents) × 100
Therefore, the calculation is:
Total milkshakes sold = (48 / 40%) × 100 = (48 / 0.4) = 120 milkshakes.
Consequently, the ice cream shop sold a total of 120 milkshakes that day.
