Robert has 12 coins consisting of nickels and dimes. If the total value of his coins is one dollar, how many coins of each type does he have?
Answer provided by our tutors
8 dimes and 4 nickels
each dime is worth 10 cents, so 8 times 10 is 80
4 nickels, each work 5 cents, is 20 cents
80+20=100
8+4=12
