Lian has $1.00. She has only nickels and dimes. Lian has twice as many dimes as nickels. How many dimes does she have?

Anna11 [10]

Answer: 8

Step-by-step 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.
