Answer:
c. 9a^8+24a^4+16
Step-by-step explanation:
Answer:
First consider the original amount.
Then consider the rate of tax or markup
To find the tax or markup, multiply the rate by the original amount.
To find the total cost, add the tax or markup to the original amount.
Step-by-step explanation:
Example
A phone has a listed price of $790 before tax. If the sales tax rate is 6.5% find the total cost of the phone with sales tax included. Round your answer to the nearest cent as required.
Solution
Step 1:
List price of the phone = $790
Sales tax rate = 6.5%
Step 2:
Sales tax = 6.5% of 790=0.065×790=51.35
Step 3:
Total cost of phone including sale tax = list price + sales tax
= 790+51.35
= $841.35

Answer:
x = 45/17
Step-by-step explanation:
We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.

Answer:
It makes the calculation easy and quick.
Step-by-step explanation:
- <em>Commutative Property of multiplication</em>
- <em>The product of two or more real numbers is not affected by the order in which they are being multiplied. In other words, real numbers can be multiplied in any order because the product remains the same. </em>
<u>When you multiply as it is given:</u>
- 5×87×2=870
- Step 1) 5×87 = 435
- Step 2) 435×2 = 870
<u>Using the commutative property makes it much easier:</u>
- 5×2×87 = 870
- Step 1) 5×2 = 10
- Step 2) 10* 87 = 870
