A money collection has $3.00 worth of coins: nickels, dimes, and quarters. The ratio of nickels to dimes to quarters is 3:2:1 How many quarters are in the collection?

$\color{Red}{AnsWer:=>}$

n + d + q = $3.00                           (they provide a ratio) 

3:2:1 = $3.00                                 (substituting values)

3(.05) + 2(.10) + 1(.25)   

.15 + .20 + .25

.60 = is the value of the ratio   

let's divide the $3.00 by the .60 to get 5

let's now multiply the value of 5 to the ratio and solve the question...

3(5): 2(5): 1(5)

15 nickels

10 dimes

5 quarters
