When you divide something by 10, yo move the decimal place one place to the left so exg
20.0/10=2.0
so divide by 1000 means move the decimal place 3 places to the left so if you had 20,000.0/1000=20.0 so
6.82/1000=0.00682
Answer:
The sales tax rate of an item that costs $4 is 8%
Step-by-step explanation:
An item costs $4 before tax
The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%
The calculation is incorrect, because the slope is defined as
![m_{AB} = \dfrac{y_A-y_B}{x_A-x_B}](https://tex.z-dn.net/?f=m_%7BAB%7D%20%3D%20%5Cdfrac%7By_A-y_B%7D%7Bx_A-x_B%7D)
So, Emma has inverted numerator and denominator: she has calculated the inverse of the slope.
The correct calculation would be
![\dfrac{300-900}{180-165} = \dfrac{-600}{15} = -40](https://tex.z-dn.net/?f=%20%5Cdfrac%7B300-900%7D%7B180-165%7D%20%3D%20%5Cdfrac%7B-600%7D%7B15%7D%20%3D%20-40)
