Dimes= $0.10
Nickels=$0.05
$1.10 could hold 11 dimes or 22 nickels, but there on only 15 coins are in this total.

Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:

From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is



The second choice is correct
