Question

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.
answer attempt 2 out of 2
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 candies left in the bag depends on the number of minutes eating.
a function relating these variables is ( n(x)=100 - 5x ).
so ( n(7)= ), meaning after eating candies for 7 minutes there would be candies left in the bag.

Explanation:

Step1: Substitute \(x = 7\) into the function

We have the function \(N(x)=100 - 5x\). When \(x = 7\), we substitute \(x\) into the function: \(N(7)=100-5\times7\).

Step2: Calculate the value

First, calculate \(5\times7 = 35\). Then, \(100-35=65\).

Answer:

\(65\)
