Answer:

The correct option is A.

Step-by-step explanation:

The equation of best fit is

y=8x+20

Where, y is time needed to produce batches of different numbers of items and x is number of items in a batch.

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

On comparing both equations we get m=8 and b=20.

It means initial time is 20 or it takes about 20 minutes for the equipment to warm up.

Since m=8, so the production time increases by 8 minutes as the number of items in a batch increases by 1.

Therefore, the correct option is A.

Answer:  $15.00 per person.
______________________________
Explanation:
______________________________
 Given that there are "4 people" (that is, "Kianna and three friends");
____________________________________________________
and a total of "$58.49" ; to be divided equally among 4 (four) people;
______________________________
 we are asked to <em><u>estimate</u></em> the amount that EACH person will pay.
______________________________
For an <em><u>ESTIMATE</u></em>,  $58.49 is ABOUT $60.00; or "60 dollars". ;

and (60 dollars) / 4 = 15 dollars {$15; or $15.00}. 

60/4 = 15;  or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.
