Jonah and three of his friends are splitting the dinner bill equally among theme selves. There total bill came to be $86 before

Oksana_A [137]

Answer: Required expression: $\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}$

Each person need to pay =$ 26.66

Step-by-step explanation:

Given: Bill amount = $86

Tip percent = 18%

Sales tax = 6%

Now, total bill = (Bill amount ) + 18% of (Bill amount ) + 6% of (Bill amount )

= $[ (86) + 18% of (86 ) + 6% of (86 )]

= $[ (86) + 0.18 x(86 ) + 0.06 x (86 )]

Total persons = 3+1 = 4

Each person need to pay= $\dfrac{\text{total bill}}{4}$

$=\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}\\\\=\dfrac{[ (86) (1+ 0.18 +0.06 )]}{4}\\\\=\dfrac{86(1.24)}{4}=\dfrac{106.64}{4}=26.66$

So, each person need to pay =$ 26.66

Create a function that has a derivative of f(x) = 2x + 1 at a given input value of your choice.

madreJ [45]

F(x) = (x^2) + x + C at (1,1)

1 = 1 + 1 + C

-1 = C

so,

F(x) = (x^2) + x - 1
