we have that
the total cost is
In this equation the term 30h represent the cost due to h hours at at unit of 30
and the term 0.040(30h) is equal to calculate the 4% of (30h)
so
in this problem the tax rate is equal to 4%
therefore
<u>the answer is</u>
The term 0.040(30h) represents the amount of tax she must pay
6x-9=15
6x=24
x=4
Therefore the answer is A.
Hope this helps :)
Answer: 0.11429 (Rounded to fifth decimal place)
Solution:
The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.
<u>Simplifying the distributive property.</u>
- => a(b - c)
- => (a x b) + (a x -c)
- => ab - ac
Hence, the simplified expression is ab - ac.
