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
