"Dollars" should be plural.
This is correct:

when 'in ' precedes a noun, it should be always singular right?
Wrong. There is no such rule, and words following 'in" are either singular or plural depending on the meaning -- depending on how many there are.
you look better in person than in picture. OKAy
you look better in persons than in pictures. NO
You are correct here, but not because all nouns following "in" are singular. The reason "in person" is correct is because it is an expression, an idiom.
Examples of correct sentences:
Darryl's dog loves riding in cars.
The first time he rode in a car, he was just a puppy.
Since then, he rides in cars whenever he can.
In case of fire, break this glass.
Here is how to solve the math problem in cases like this.
However, many expressions starting with "in" don't have a plural form.
- in trouble
- in luck
- in sickness and in health
- in the event of
- in the money
But some do:
"When we were kids, we couldn't stay in bed all day."
"When we were kids, we slept in beds of eiderdown."
And some expressions have only a plural form:
"The moon walked on the ocean in shoes of silver light."
"Walk a mile in my shoes."
"In dreams you're mine all the time."
(but you can say, "I saw her in a dream.")
