We have been given that the number of students enrolled at a college is 18,000 and grows 4% each year. We are asked to find number of students after 22 years.
We will use exponential growth function to solve our given problem.
We know that an exponential growth function is in form , where
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
x = Time
To find number of students after 22 years, we will substitute in our function.
Therefore, there will be approximately 42,659 students after 22 years.
The number of ounces of cereal in the third box is 32.
<u>Explanation:</u>
Given-
10 oy box = $3
Price of 1 ounce box = $3/10
= $0.3
20 oy box = $5
Price of 1 oy box = $5/20
= $0.25
Therefore, it is beneficial to buy a 20 oy box as it is comparatively cheaper than the 10 oy box.
Third box of cereal = $8
$5 is the price of 20 oy box
$8 will be the price of x oy box
So,
Therefore, the number of ounces of cereal in the third box is 32.
