After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8 percent.

lisov135 [29]

Answer:

Tip = $10.52

Tax = $4.21

Total bill = $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax bill = $52.60

Tip to waiter = 20% of the pre-tax amount

Tip to waiter =

$20\%\times \text{Pre-tax amount}\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52$

Thus, $10.52 was given to waiter.

Tax on bill = 8% of the pre-tax amount

Tax =

$8\%\times \text{Pre-tax amount}\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21$

Thus, tax on bill was $4.21.

Total bill =

Pre-tax amount + Tax + Tip

$=52.60 + 4.21 + 10.52\\=67.33\$$

Thus, the total bill is $67.33

Let f(x)=x2 -4x and g(x) =7-x find (fg)(2)

marta [7]

Step-by-step explanation:

f(x) = x² - 4

g(x) = 7 - x

= (fog)(2)

= x² - 4

= (7 - x)² - 4

= (7 - 2)² - 4

= 5² - 4

= 25 - 4

= 21

(fog)(2) = 21
