ken, Mike and Ariel are eating out at their favorite restaurant. They each order a sandwich combo and plan to split the entire bill evenly. The service they receive at the restaurant is amazing, so they decide to leave a 30% tip. Their bill total is $50.88 before tax.

To find out how much each person needs to pay, we first need to calculate the amount of tip they need to leave.

The bill total before tax is $50.88. If they want to leave a 30% tip, the amount of tip they need to pay is 30% of $50.88.

Tip amount = 30% of $50.88 = (30/100) * $50.88 = $15.26

Now, let's calculate the total amount they need to pay, including the tip.

Total amount = bill total + tip amount = $50.88 + $15.26 = $66.14

Since they plan to split the bill evenly, each person needs to pay 1/3rd of the total amount.

Each person's share = 1/3 of $66.14 = (1/3) * $66.14 ≈ $22.05

So, Ken, Mike, and Ariel each need to pay approximately $22.05.
