Mx. Ortiz has $15.68 in pennies and nickels. If there are three times as many nickels as pennies, how many pennies and nickels does Mx. Ortiz have?
p = pennies 1p = value of pennies
n = nickles..... this equals 3p ( this is given in the Q) ....value of nickles = 5 (3p)
summed thes equal 1568
1p + 5(3p) = 1568
16p = 1568 solve for p, the number of pennies then # nickles = 3 * p
