Kyle has 13 coins in his pocket that are either quarters or nickels. He has $2.05 in his pocket in coins.

Let q represent the number of quarters and n represent the number of nickels. The following system of equations represents this situation:

q+n=13

0.25q+0.05n=2.05

How many nickels and quarters does Kyle have?

Respuesta :

Kyle would have 7 quarters and 6 nickels. 7 + 6 = 13
0.25 * 7 = 1.75 & 0.05 * 6= 0.30.  1.75 + .30 = 2.05
