Using the described method, if Denver has a population of 700,000 and 70% use ATMs, with each ATM serving about 1,500 people, how many ATMs are needed to serve the users?

Explanation:
To determine how many ATMs are needed, first convert the percentage of people who use ATMs into a number of users, then divide by how many people each ATM can serve, rounding up to ensure full coverage. Compute 0.7 times 700,000 = 490,000 users. Each ATM serves about 1,500 people, so 490,000 ÷ 1,500 ≈ 326.67. Since you can’t have a fraction of an ATM, round up to 327. Therefore, 327 ATMs are needed.
