Answer: <em>y = 4</em>
Step-by-step explanation:
<em>y - 4 = -2(x + 3)
</em>
<em>(-3, ? )</em>
<em>y - 4 = -2(- 3 + 3)
</em>
<em>y - 4 = -2 · 0</em>
<em>y - 4 = 0</em>
<em>y - 4 + 4 = 0 + 4</em>
<em>y = 4</em>
<em>(-3, </em><em>4</em><em>)</em>
Fraction of tank drops in every 10 minutes = 1/3 inches.
We need to find the expected change in the tank's water level after 2.25 hours.
Let us convert 2.25 hours in minutes.
1 hours = 60 minutes.
2.25 hours = 2.25 × 60 = 135 minutes.
<em>We need to divide 135 by 10.</em>
We get 13.5.
Now, we need to <em>multiply 1/3 by 13.5</em>, we get.
13.5/3 = 4.5 inches.
<h3>So, tank would drop 4.5 inches after 2.25 hours.</h3>
$7.50 * 18.5 hrs = $138.75
$7.50 * 20 hrs = $150
138.75 + 150 = 288.75
She raises the price by ¢0.75
So now it is $8.25 per hour
(I guessed on a calculator and got it right)
Multiply 8.25 by 35 and you get 288.75
Your answer is 35
