First, we need to figure out 10% of fifteen.
So, we multiple 15 by 10% (or 0.1 in simpler terms).
That gives us 1.5, which is our mark-up price.
So, finally we add the markup price to the original price to obtain the selling price.
1.5 + 15 = 16.5
The owner charges $16.50 for 1kg of sugar!
The answer to this problem is 396cm
Answer:
8 times 10 is 80
Step-by-step explanation:
The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols

<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.
The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:
</span>

Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>
The answer is C. You pay $128 in the third hour for both. Hope this helped
