Lian has $1.00 she has only nickels and dimes. lian has twice as many dimes as nickels how many dimes does she have?
a) 5
b) 8
c) 4
d) 3
e) 7

B) 8

Step-by-step explanation:

Because she has twice as many dime as nickels, that automatically makes 5, 3, and 7 invalid answers since you cannot have whole halfs of them.

8 dimes = 80 c.

8/2 = 4

4 nickles = 20 c.

80c + 20c = $1.00

The number of dimes she has is; B: 8 dimes

Liam has $1.

She has twice as many dimes as nickels.

This means that;

2n = d

Now, from conversions ;

$0.5 = 1 nickel

$0.1 = 1 dime

Thus possible combination to get $1 is;

4 nickels and 8 dimes

Thus;

4(0.5) + 8(0.1) = $1

Thus, he has 8 dimes and 4 nickels
