The change is the remaining money that is needed to take from the seller so a change of Umberto will be $6.62.
<h3>What is subtraction?</h3>
To subtract in mathematics is to take something away from a group or a number of objects.
The group's total number of items decreases or becomes lower when we subtract from it.
Given that,
Umberto buys a game for $7.89 and some batteries for $5.49.
Total money of buying = 7.89 + 5.49 = $13.38
Now he gives a $20 bill.
Remaining (change) = 20 - 13.38
⇒ $6.62
Hence "The change of Umberto will be $6.62".

Hi, I'm sorry but I don't know what the box method is but the answer for question 15 is 14472 and the answer for question 16 is 17510.
-x + 10 = 3x + 22
-12 = 4x
x = -3
Answer:
Probably 5
Step-by-step explanation:
I don't fully understand the question but I am thinking that the total factor is 10 and divide 2 from it. What is left is function g which is probably going to be 5. Just an estimate. Hope it helps anyways. :)
