Answer 2

Answer: (8)($4)

Answer with an explanation:

What we need to know: Any number 5 or higher is automatically rounded up, any number 4 or lower is automatically round down. Also if the number is after the decimal you can say 5 or higher with a zero because it doesnt do anything to the number, so you could say .50 or higher or .40 or lower and if it has three decimal places just add another zero so it would be .500 higher or .400 lower.

So, 7.9 is rounded up to 8.0 because 9 is 5 or higher.

$3.89 is rounded up to $4.00 because .89 is higher than .50.

Now just take off the zeros from 8.0 and $4.00 to get (8)($4)

Hope this helps.
