Answer:
8189.11
Step-by-step explanation:
If 8900 is 100% and we need to find 15% we would multiply 8900 and 15 then divide by 100 and that equal 1335 so we would then subtract 1335 from 8900 because it is 15% off, which equals 7565, so now 7565 is 100% and we need to add the 8.25% tax, so we multiply 7565 and 8.25 then divide by 100 which equals 625.11 then we add 7565 and 625.11 which equals 8189.11
Their beginning time was 16.06 minutes.
<u>Step-by-step explanation:</u>
The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes, take it as
. Then they are able to reduce that time by 10 minutes, take it as
. Let ‘X’ be the time in minutes at the beginning.
Given that their final time is 3.96 minutes, then their beginning time can be calculated as below,


By substituting the values, we get

Hence, their beginning time was 16.06 minutes.
You want to find the time <em>t</em> such that

Divide both sides by $200 :

Take the logarithm of both sides:

Divide both sides by 0.04 and solve for <em>t</em> :
