Answer: 10d+5n+p
This is the total value of the coins in cents
To convert this to dollars, divide by 100. So the total value in dollars is (10d+5n+p)/100.
The three terms are
- 10d = value of all the dimes only
- 5n = value of all the nickels only
- p = value of all the pennies only
------------
Let's look at an example with actual numbers.
- d = 9 dimes
- n = 3 nickels
- p = 5 pennies
I picked three whole numbers at random.
So,
- 10d = 10*9 = 90 cents comes from the dimes only
- 5n = 5*3 = 15 cents comes from the nickels only
- p = 5 cents comes from the pennies only
The total value is 10d+5n+p = 90+15+5 = 110 cents aka 110/100 = 1.10 dollars.
