Question

A store manager collects information about the number of people who visit his store each week. the information, collected over a 3-week period, is listed below. • the number of people that visited the store in week 1 was 3,200. the number of people that visited the store in week 2 was 10% more than week 1. • the number of people that visited the store in week 3 was 15% more than week 2. how many people visited the store in week 3?

Answer 1

To determine the number of people who visited the store in week 3, we calculated the 10% increase from week 1 to week 2, and then the 15% increase from week 2 to week 3, resulting in 4,048 people.

Step-by-step explanation:

The question involves calculating the number of people who visited a store in week 3, based on percentage increases from the previous weeks. Initially, 3,200 people visited the store in week 1. In week 2, there was a 10% increase from week 1. To find the number of people who visited in week 2, we calculate 10% of 3,200 and add it to the initial amount. So, that would be 320 (which is 10% of 3,200) plus 3,200, giving us a total of 3,520 people for week 2.

In week 3, there was a further 15% increase from the number of visitors in week 2. We calculate 15% of 3,520 which is 528 and add this to the week 2 total. Thus, 3,520 + 528 gives us 4,048. Therefore, 4,048 people visited the store in week 3.

Answer 2

To find the number of visitors in week 3, calculate a 10% increase on week 1's visitors for week 2, and then a 15% increase on week 2's visitors for week 3. The answer is 4,048 visitors in week 3.

Step-by-step explanation:

The store manager is collecting data on the number of people visiting the store each week. To determine the number of visitors in week 3, we need to apply percentages to find the increase from week 1 to week 2, and then from week 2 to week 3.

In week 1, 3,200 people visited the store. In week 2, there was a 10% increase, so we calculate this by multiplying 3,200 by 10% (or 0.10): 3,200 × 0.10 = 320. Therefore, week 2 had 3,200 + 320 = 3,520 visitors.

Then, week 3 had a 15% increase over week 2. We calculate 15% of week 2's visitors: 3,520 × 0.15 = 528. Adding this to the week 2 figure, week 3 had 3,520 + 528 = 4,048 visitors.
