Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula . In this case, m is the rate of change, time is x, and the carrots remaining is y.
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.

Answer:
45 miles per hour
Step-by-step explanation:
The second bit of information is completely irrelevant. To calculate speed, you have to use the equation distance divided by time. If the distance of the trip is 90 miles and it took two hours, 90/2 = 45.
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.
n% = percentage of people that chose hot chocolate
150 x n% = 72
n / 100 = 72 / 150
n = 48
= total people x hot Choco percentage
= 500 x 48%
= 240
