Answer: 8

Explanation:

Given

Lian has
\$1.00 and she has twice as many dimes as nickels

Suppose she has
x nickels

So, the number of dimes is
2x

Nickel is equivalent to 5 cents and dime is equivalent to 10 cent


\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4

Therefore she has 8 dimes with her.
