Answer
Find out the number of hours when the cost of parking at both garages will be the same.
To prove
As given
There are two parking garages in beacon falls .
As given
Let us assume that the y is representing the cost of parking at both garages will be the same.
The total number of hours is represented by the x.
First case
Garage a charges $7.00 to park for the first 2 hours ,and each additional hour costs $3.00 .
As garage charges $7.00 for the first 2 hours so the remaning hours are (x -2)
Than the equation becomes
y = 3.00 (x -2) + 7.00
written in the simple form
y = 3x - 6 +7
y = 3x + 1
Second case
Garage b charges $3.25 per hour to park.
than the equation becomes
y = 3.25x
Compare both the equations
3x +1 = 3.25x
3.25x -3x = 1
.25x = 1
x = 4hours
Therefore in the 4 hours the cost of parking at both garages will be the same.
I=PRT/100
1. Make R (rate) subject
R/100= I/PT
2. Substitute and calculate
r/100= i/pt
r/100= 40/400 × 1
(<em>4</em><em>0</em><em> </em><em>i</em><em>s</em><em> </em>from 440-400.<em>T</em><em>h</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>e</em><em>r</em><em>e</em><em>s</em><em>t</em>)
r/100= 0.1
r/100×100= 0.1×100
r=10% (interest rate per year)
To confirm
I=PRT
I= 400×10/100×1
I= $40 (Interest)
Answer:
<h2>5 quarts</h2>
Step-by-step explanation:
Let's think through this bit by bit.
<em>10 lbs * 16 oz/lb = 160 oz. of apples.</em>
In the proportion below, we can see we simply divide by 8, in terms of magnitude.
8 oz -> 1 cup
160 oz -> 160/8 -> 20 cup
20 cups! Is it the answer? NO! They're asking for it in units of <em>quarts, not cups.</em>
We must remember that 1 quart = 4 cups.
20 cups * 1/4 qt/cups = 5 quarts

Answer: $5.16</h3>
==================================================
Work Shown:
72% = 72/100 = 0.72
72% of $3.00 = 0.72*3.00 = 2.16
The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars
-------
We can find this answer through this alternative route:
1.72*3 = 5.16
The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
