**Miguel**, Thursday, February 24, 2011 at 12:41amlet nickels be 'n' and quarters be 'q'

n + q = 24

q = 10 + n

substitute q into the equation

n + (10 + n) = 24

subtract 10 from both sides

10 + 2n = 24

2n = 14

divide by 2 on both sides

n=7 or 7 nickels or 35cents (7*5 cents)

plug 7 back into the second equation because they told us Victoria has 10 more quarters than nickles. So she must have 17 quarters.

7 + 10 = 17 quarters

17 * 25 cents or .25 = 4.25

$4.25 + $.35 = $4.60
