15. A fast food outlet knows that 55% of its customers purchase fries. If the store had 1200 customers in a day, then the number who bought fries was
Answer: A
660 customers bought fries.
To determine the number of customers who purchased fries, we calculate 55% of the total customers, which is 55% of 1200. This results in 660 customers.
A) 660
This option is correct because when calculating 55% of 1200, the equation is 0.55 * 1200 = 660. This aligns perfectly with the given percentage and total number of customers.
B) 640
This option is incorrect as it suggests that 640 customers purchased fries. To arrive at this number, one would have to miscalculate the percentage or total, which does not align with the 55% figure provided.
C) 620
This option is also incorrect. It implies that 620 customers bought fries, which is less than the actual calculated amount of 660. This does not reflect the 55% of 1200 customers.
D) 540
This option is incorrect as well. It indicates that 540 customers purchased fries, which is significantly lower than the correct calculation. This does not meet the 55% threshold of the total customer count.
Conclusion
The correct answer is definitively 660, as it accurately reflects 55% of 1200 customers. The other options fail to meet this calculation and underestimate the number of customers purchasing fries based on the provided percentage.
