Height of the water after 3 minutes is 31.25 inches

<h3><u>Solution:</u></h3>

Given that height of the water in a fish pond is 42.5 inches

Water is being drained from the pond at a rate of 3.75 inches per minute

<em><u>To find:  height of the water after 3 minutes</u></em>

According to given information,

Water drained in 1 minute = 3.75 inches

<em><u>So height of the water after 3 minutes is calculated by following steps:</u></em>

1) find how much water is drained in 3 minutes

2) subtract value obtained in step 1 from total height of water in fish pond

<h3><u>Step 1:</u></h3>

water is drained in 3 minutes = Water drained in 1 minute x 3

\text {water is drained in } 3 \text { minutes }=3.75 \times 3=11.25

Thus water drained in 3 minutes is 11.25 inches

<h3><u>Step 2:</u></h3>

height of the water after 3 minutes = total height of water in fish pond - water drained in 3 minutes

height of the water after 3 minutes = 42.5 - 11.25 = 31.25 inches

Thus height of the water after 3 minutes is 31.25 inches

mike and kim invest $14,000 in equipment to print yearbooks for schools. each yearbook costs $7 to print and sells for $35. how
Zina [86]
The answer is A.) 500 Year books.

The profit they would gain from each year book would be $28 since each year book costs $7 to make and sells for $35. You would simply divide 14,000 by 28 to find how many books they would need to sell in order to get their investment back which would be 500 books. 

Hope this helps.
