How many people used the public pool altogether? There isn't enough info
Anyways,
You would write two equations and solve using substitution / elimination / graphing
one equation is:
1.5x + 2.25y = 1258.5
(x is children, y is adults)
Do you have a diagram to go with this ill be able to help if you did
Yes 3/12 cane be simplified.
3÷3/21÷3
= 1/4
Answer:
25%
Step-by-step explanation:
The first doubling, from 20 to 40 occurs in a little more than 3 years, so the multiplier each year is a little less than 2^(1/3) ≈ 1.26. That is, each year is a little less than 26% more than the previous year.
The graph also goes near the point (8, 120), so grows by a factor of 6 in 8 years. That suggests a multiplier of 6^(1/8) ≈ 1.251. Each year is about 25.1% more than the previous year.
Both of these multipliers represent yearly growth rates near 25%.
___
Using the "rule of 72", the product of doubling time and percentage growth is about 72. So, for a doubling time of 3 years, the percentage growth is predicted to be near 72/3 = 24 percent.
All of these estimates help you choose the correct answer: 25%.
Well, the interest literally mean the amount that add up to your previous capital that you invest in the past.
If you invest an amount of money and get an interest revenue out of it, the amount of your capital will be increased , not decreased
