The answer is 104.4 because 38+65 is 103. then you add the decimal part of the equation which is 37. If you are rounding to the nearest tenth it would be 104.4

38.94 rounds up to 40 as it is more than half-way between 30 & 40.
65.43 rounds up to 70. even though 65 is half-way, .43 makes it closer to 70 than 60.

40 + 70 = 110

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
