Mr. jackson sold 3 computer monitors in the first year. in the second year, he sold 4 times as many monitors as the first year. in the third year, he was able to sell 6 times as many monitors as in the first year. how many monitors did mr. jackson sell in three years?

Mr Jackson Sold 39 Computer monitors in three years.

Step-by-step explanation:

Given:

Sale of Computer Monitor in 1st year = 3

In second year he sold 4 times as many monitors as the first year.

To find Sale of Computer Monitor in 2nd year we will multiply 4 with Sale of Computer Monitor in 1st year

Hence,

Sale of Computer Monitor in 2nd year = 4 Sale of Computer Monitor in 1st year =

In the third year, he was able to sell 6 times as many monitors as in the first year.

To find Sale of Computer Monitor in 3rd year we will multiply 6 with Sale of Computer Monitor in 1st year

Hence,

Sale of Computer Monitor in 3rd year = 6 Sale of Computer Monitor in 1st year =

Now we need to find monitors sold in three years,

It can be calculate by adding Sale of Computer Monitor in 1st year and Sale of Computer Monitor in 2nd year and Sale of Computer Monitor in 3rd year.

Monitors sold in 3 years =

Hence Mr. Jackson sold 39 computer monitor in 3 year.

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
