Answer:
98.88
Step-by-step explanation:
Given: They cheered 12 rounds. Each round = 8.24
To find the total number, multiply how much one round is with the total number of rounds.
8.24
× 12
-----------
1648
+ 8240
----------
Each girl cheered 98.88 minutes. If you need this estimated, the answer would be 99 minutes.
See attached graph
because we define
x=60
We have, 15% × x = 9
or,
15
100
× x = 9
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 9 ×
x = 60
If you are using a calculator, simply enter 9×100÷15, which will give you the answer.
