Jennifer has 25 coins with a total value of $4.25. The coins are quarters and nickels. How many of each does she have?
kirill115 [55]

Answer:

15 quarters, 10 nickels

Step-by-step explanation:

q+n=25

0.25q+0.05n=4.25

multiply the first equation by -0.25 and add the second equation to it

-0.25q-0.25n=-6.25\\0.25q+0.05n=4.25
________________
                -0.2n=-2

n=\frac{-2}{-0.2} =10   has 10 nickels

q=25-n=25-10=15  has 15 quarters

10(.05) +15(0.25) = 0.5 + 3.75 = 4.25

Hope this helps
