Bailey has $2.35 in nickels and dimes. If she has 33 coins in all, find the number of nickels and dimes.

answer:

Step-by-step explanation:A nickel is worth 5¢ and a dime worth 10¢, $2.35 is 235¢

If x is number of nickels and y the number of dimes

x + y   =33, x = 33 - y

5x +10y=235  substitute for x

5(33 -y) +10y =235

165 - 5y+ 10y =235

                 5y  = 70

y = 14 and x = 19

There are  14 dimes and 19 nickels
