Let's say I work in a store and a costmer walks up to me and asks me how much are a pair of head phones. And I say $3.80. Let's say the custumer gave me $5.00. How much change will I give back to the custumr?

Answer 1

Subtract $3.80 from $5.00

5.00
- 3.80
____________

Answer 2

$1.20. The cent has to be rounded to the nearest dollar right? so I would add .80+.20=$1.00 right?

Answer 3

With money, we don't round to the nearest dollar. We round to the nearest penny. You should give $1.20 in change to the customer.

Answer 4

$1.20. $3.80 is almost $4.00 right? So that means I would give my custumer $1 and something right? Because the custumer already used his extra dollar right? And I got the .20 by rounding to the next dollar. So .80+.20=$1.00. So that's how I got $1.20.

Can I also work it out the way I just explained it?

Answer 5

Yeah. "The nearest penny" that's what I meant. Thanks. But is the way I describe it correct?
