Answer:
12
Step-by-step explanation:
The average rate of change of a function is the slope because
let 

so we just need to calculate the slope of the function over the interval [3, 5]

2340/10=234 bags of apples
hope this helps :)
The equation to calculate how many ways that "r" things can be chosen from a larger set of "n" things is:n! / [r! * (n-r)!] =
12! / (5! * 7!) =
12 * 11 * 10 * 9 * 8 * 7! / (5! * 7!) =12 * 11 * 10 * 9 * 8 / 5 * 4 * 3 * 2 =11 * 9 * 8 =792 ways
