Ben has 4 dimes and 12 nickels
<em><u>Solution:</u></em>
Let "d" be the number of dimes
Let "n" be the number of nickels
We know that,
value of 1 dime = $ 0.10
value of 1 nickel = $ 0.05
<em><u>Ben had three times as many nickels as dimes</u></em>
Number of nickels = 3 times the number of dimes
n = 3d --------- eqn 1
<em><u>The total value of his coins was $1</u></em>
<em><u>Therefore, we frame a equation as:</u></em>
number of dimes x value of 1 dime + number of nickels x value of 1 nickel = 1
![d \times 0.10 + n \times 0.05 = 1\\\\\text{Substitute eqn 1 in above }\\\\0.10d + 0.05(3d) = 1\\\\\text{Simplify the above expression }\\\\0.10d + 0.15d = 1\\\\0.25d = 1\\\\\text{Divide both sides of equation by 0.25 }\\\\d = 4](https://tex.z-dn.net/?f=d%20%5Ctimes%200.10%20%2B%20n%20%5Ctimes%200.05%20%3D%201%5C%5C%5C%5C%5Ctext%7BSubstitute%20eqn%201%20in%20above%20%7D%5C%5C%5C%5C0.10d%20%2B%200.05%283d%29%20%3D%201%5C%5C%5C%5C%5Ctext%7BSimplify%20the%20above%20expression%20%7D%5C%5C%5C%5C0.10d%20%2B%200.15d%20%3D%201%5C%5C%5C%5C0.25d%20%3D%201%5C%5C%5C%5C%5Ctext%7BDivide%20both%20sides%20of%20equation%20by%200.25%20%7D%5C%5C%5C%5Cd%20%3D%204)
<em><u>Substitute d = 4 in eqn 1</u></em>
n = 3(4)
n = 12
Thus Ben has 4 dimes and 12 nickels
