Katyanochek1 [597]

Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.

<h3>How much will Big Brothers, Inc. pay annually?</h3>

This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.

Formula is:

Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate

Solving gives:

267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%

267,999 = Amount x 4.46865

Amount = 267,999 / 4.46865

= $59,973.15

Lina20 [59]
The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are <span>101,949 fewer people  than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people

Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = </span>351,875 + 249,926 = 601,801 people

Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people
