Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the <u>percent rate of change.</u>
Here is how we will do this problem:
<h3><u>
First, Set up a ratio:</u></h3>
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
<h3><u>
Next, we will divide. the ratio.</u></h3>
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
<h3><u>
Convert the fraction to a decimal.</u></h3>
Fraction - 42/15
Decimal - 2.8
<h3>
<u>Make the decimal to a percent.</u></h3>
Decimal - 2.8
Percent - 28%
<u>Add a zero to the 28.</u>
<h2><u>
Our answer is 280%</u></h2>

Answer:
6 1/2 divide 3 2/3 = 39/22
Step-by-step explanation:
x² + 3x - 10 = 0
x = -(3) ± √((3)² - 4(1)(-10))
2(1)
x = -3 ± √(9 + 40)
2
x = -3 ± √(49)
2
x = -3 ± 7
2
x = -3 + 7 U x = -3 - 7
2 2
x = 4 U x = -10
2 2
x = 2 U x = -5
Solution Set: {2, -5}
Answer:
1. 3600 x 25 ÷100 =900
there fore the discount price is p900
3. it means if you add to integers you get 143
so x +x+1=143
2x +1=143
2x+1-1=143_1
2x=142
2x/2 =142/2
x=71
x+1=71+1=72
