Martin was going to the market to buy apples. the price for apples is $3.50 times the number of apples bought plus one-dollar tax. write a polynomial function a that represents the price of apples in terms of n. if martin bought 3^3 amount of apples. how much did the apples cost?

Polynomial Function: 3.5n + 1

Total Price of the Apples: $32.50

Step-by-step explanation:

The polynomial function is 3.5n + 1:

The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.

The total price of the apples:

3.5n + 1 ; n = 3^3 = 9

(3.5 x 9) + 1

31.5 + 1

32.5

$32.50

=====================================

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

answer is 67%
