Let initial price be = x = 3.24
final price = y = 4.05
Difference = 4.05 - 3.24
= 0.81
Percentage increase = 0.81 / 3.25 × 100
= 25 %
Answer:
3/4
Step-by-step explanation:
Slope = rise over run
Rise = (-5) - (-2)
Run = 2 - 6
-3/-4

Answer:
Option b
Explanation:
To solve this problem you need to plug in the values provided and determine if they make the equation true.
Step 1 - Plug in the values for x and y given in option a. Determine if all values make the equation true.
y = 3x + 1
1 = 3(0) + 1
1 = 1 {true}
y = 3x + 1
9 = 3(2) + 1
9 = 7 {not true}
Since the second ordered pair does not make the equation true, this is not the correct answer.
Step 2 - Plug in the values for x and y given in option b. Determine if all values make the equation true.
y = 3x + 1
1 = 3(0) + 1
1 = 1 {true}
y = 3x + 1
7 = 3(2) + 1
7 = 7 {true}
y = 3x + 1
19 = 3(6) + 1
19 = 19 {true}
Since all of the ordered pairs given in Option b make the equation true, this is the correct answer. To double check, you can do the same process for option c to make sure it is not true.
Step 3 - (Optional step) Plug in the values for x and y given in option c. Determine if all values make the equation true.
y = 3x + 1
-1 = 3(0) + 1
-1 = 1 {not true}
Since the first ordered pair given does not make the equation true, this is not the correct answer.

Answer: Matt</h3>
==============================================
Explanation:
5 cupcakes : 20 min
5/5 cupcakes : 20/5 min
1 cupcake : 4 min
Carolyn eats 1 cupcake every 4 minutes
----------
6 cupcakes : 22 min
6/6 cupcakes : 22/6 min
1 cupcake : 3.67 min
Matt eats 1 cupcake every 3.67 minutes (roughly).
Matt is the faster eater since his time value per cupcake is smaller.
