Hey there! :D
When you are writing the price for something, you usually include two decimal points, for example, $29.99, $3.47, etc.
We would round the 7 up or down depending. If the number behind it is 5 or more, we will round it up to 8, if it is less, we will round it down.
4<5
$83.57 <== the answer
I hope this helps!
