A coin collection is made up of 34 coins comprised of nickels and dimes. The total value of the collection is $1.90. How many di
mes and nickels made up these collections?
1 answer:
Answer:
x = nickels
y= dimes
x + y = 34
.05x + .10y= $1.90
-.10x - .10y = -3.40
-.05x + .10y = 1.90
-.05x = -1.50
x = 30 nickels
30 + y = 34
y = 4 dimes
