Question

The table shows the number of candies packed by machine c. the equation shows the number of candies packed by machine D. In both representations, x is a measure of the number of minutes and y is a measure of the number of candies packed. How many more candies could machine d pack than machine c in 11 minutes

Answer 1

Answer: 605 candies

Explanation:

Machine C shows a table where 150 candies are added every 2 minutes (which equals 75 candies per minute). Extend the table to show how many candies are made in 11 minutes:

x y

(minutes) (candies)

2 150

4 300

6 450

8 600

10 750

11 825

Machine D productivity is given by the equation y = 130x

when x = 11 minutes, y = 130(11)

= 1430 candies

The difference between machines C and D is: 1430 - 825 = 605
