8 friends went out to dinner. Reynaldo wanted to pay for his and his girlfriend's part of the bill, as well as the tip for the whole table. The total bill was $219.01 with the gratuity (standard 18%) already added. Reynaldo knows he is responsible for about $50 worth of food, how much should he contribute in total?

let x = total bill without tip
x + 0.18x = 219.01
1.18x = 219.01
x = 219.01 / 1.18 = $185.60
tip = 0.18x = 0.18*(185.60) = $33.41
reynaldo should contribute $50 + $33.41 = $83.41
x + 0.18x = 219.01
1.18x = 219.01
x = 219.01 / 1.18 = $185.60
tip = 0.18x = 0.18*(185.60) = $33.41
reynaldo should contribute $50 + $33.41 = $83.41
