Answer:
To calculate the average value, we multiply the individual value of the components, by the number of the component and then sum the values we get. Finally, we divide the sum by the number of components as such:
Marble value: 25 * 2 = 50 cents
Gum value = 10 * 10 = 100 cents
Nickel value = 15 * 5 = 75 cents
Total value = 225 cents
Average value = 225/ 50
Average value = 4.5 cents
