George saves nickels and dimes for tolls. If he has 28 coins worth 2.60. how many are nickels and how many are dimes Answer this question by using system of equation?
7 quarters 2 dimes 4 nickels
He has jillian.
To find out how many coins are worth $1.45 using only dimes and nickels, we can set up a system of equations. Let x be the number of dimes and y be the number of nickels. The value of x dimes is 10x cents, and the value of y nickels is 5y cents. We can write the equation 10x + 5y = 145 (since $1.45 is equivalent to 145 cents). To solve for the number of coins, we need to find a combination of x and y that satisfies this equation.
117 nickles
