Jacob bought a bag containing 100 small candies. He starts eating the candies at a rate of 5 candies per minute. Answer the questions below regarding the relationship between the number of minutes eating and the number of candies left in the bag.
The independent variable, x, represents the number of minutes eating, and the dependent variable is the number of candies left in the bag, because the number of minutes eating depends on the number of candies left in the bag.
A function relating these variables is N(x)= blank*.
So N(7)= blank*, meaning
-7 candies would be left after
-after eating candies for 7 minutes there would be
blank*
-candies left in the bag
-minutes of eating
.
A function relating these variables is N(x) = 100 - 5x.
So N(7) = 100 - 5(7) = 100 - 35 = 65
This means after eating candies for 7 minutes there would be 65 candies left in the bag.
