The daily lunch special at Bertan’s favorite restaurant costs P6.95, not including tax. The final cost of the lunch special with tax is P7.52. What is the tax rate, to the nearest tenth of a percent, charged for the lunch special?

Sagot :

[tex] \frac{7.52-6.95}{6.95} = \frac{0.57}{6.95} =0.0820[/tex] 

(0.0820 is not exact)

We change it to rate
[tex]0.0820=8.2 percent[/tex]

8.2% is the tax rate
P6.95 / P7.52 = 0.92
