Make an equation for the following word problem:
Mr. Werner has 15 coins in his pocket. Some of them are nickels, and some of them are times. If the coins total is $1.05, how many coins are nickels?

Respuesta :

n is for nickels, d for dimes
n+d=15 because the total number of coins is 15.
5n+10d = 105 because that’s how many pennies worth of your coins you would have (5 pennies per nickel, 10 per dime). The solution to this is you would have 8 dimes and 7 nickels.
