there are a couple ways to do this perhaps the easiest was is to add up all the money, then divide by the number of coins there are

3. anonymous

in other words, it is really just the "average"

4. anonymous

so 12?

HI!!

6. misty1212

just like the last one lets count the money first

7. misty1212

$17+5\times 11+8\times 10+14\times 25$

8. misty1212

i get $$502$$

9. misty1212

then divide that by the number of coins

10. misty1212

i get 50

11. misty1212

final answer $\frac{502}{50}$ in pennies
