Answer 1

The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.

According to the question,

We have the following information:

Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.

The number of $5 and $1 bills are n.

a) So, we will have the following expression for the total money he has:

1*20+3*10+5n+n

20+30+5n+n

Now, adding the numbers together and the terms with the same variable together:

$(6n+50)

b) Now, when n = 5:

$(6*5+50)

$(30+50)

$80

Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
