Problema Solution
Billy has 16 coins in a jar. The jar contains only nickels and dimes. If the coins are worth $1.10, how many nickels does Billy have?
Answer provided by our tutors
10 nickels and 6 dimes. 10 (number of nickels) times 5 (how much each nickel is worth) is 50 cents. 6 (number of dimes) times 10 (how much each dime is worth) is 60 cents. 50 (cents in nickels) plus 60 (price in dimes) is 110 or $1.10. 10 (number of nickels) plus 6 (number of dimes) is 16.
