Step-by-step explanation:
Multiply by 1
combine like terms
Combine the second
rearrange terms

The lowest number is 2/1 or 2.
reduce 8/4 to 4/2 which can be reduced to 2/1
Answer:
The error is at step (3) .
The correct step (3) will be,
![\log_{b}(\frac {b^{x}}{b^{y}})](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28%5Cfrac%20%7Bb%5E%7Bx%7D%7D%7Bb%5E%7By%7D%7D%29)
=
[by using the laws of indices]
All other steps are correct.
Step-by-step explanation:
The error is at the step (3) , because the student has tried to prove the quotient rule of logarithms by using the property i.e., 'The quotient rule of logarithm' itself , i.e. ,by assuming the property does hold before proving it. So, the proof is fallacious.
The correct step (3) will be,
![\log_{b}(\frac {b^{x}}{b^{y}})](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28%5Cfrac%20%7Bb%5E%7Bx%7D%7D%7Bb%5E%7By%7D%7D%29)
=
[by using the laws of indices]
All other steps are correct.
Given:
Mr. Rodriguez : 6.25
Mrs. R 7.50
2 children @ 4.99 each <u> 9.98</u>
Subtotal: 23.73
Sales tax 7.25% 1.72 *23.73 x 7.25%
Total tip 15% <u> 3.56 </u> *23.73 x 15%
Grand total $29.01
Tips should be applied to pre-tax amount not post-tax. However, some companies compute tip based on post-tax amount. This means that the tip you are paying is computed based on the total amount of the meal as well as the sales tax you paid for the meal.
