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 Ho

Katyanochek1 [597]

They provide all the needed data...

n + d + q = $3.00 (they provide a ratio)
3:2:1 = $3.00 (let's enter the value of each)
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
