Answer:
Step-by-step explanation:
The area of a square is found in the formula
We have the Area value so we will plug it in:
Take the square root of both sides to undo the square on the s to get that
s = 9
<h3><em><u>The equation to find the number of hours for which the total cost will be the same for the two services is:</u></em></h3><h3>12 + 5h = 18 + 3h</h3>
<em><u>Solution:</u></em>
Let "h" be the number of hours
Given that,
<em><u>Derrick's Dog Sitting charges $12 plus $5 per hour</u></em>
Cost : 12 + 5(number of hours )
Cost : 12 + 5h ---------- eqn 1
<em><u>Darlene's Dog Sitting charges $18 plus $3 per hour</u></em>
Cost: 18 + 3(number of hours)
Cost: 18 + 3h ---------- eqn 1
<em><u>For eqn 1 = eqn 2, the number of hours for the total cost will be the same for the two services</u></em>
Therefore,
12 + 5h = 18 + 3h
Thus option A is correct
Get more specific. Don't look at days know, look at hours. Since there are 24 hours in a day, and there are 17 days, do 17*24 to get a total of 408 hours. Divide this by 2 to get 204 hours (or 8 hours 30 minutes) for each person's trip.
