Jake, Judy, and Lynn went out to lunch. Including tax and tip, Jake paid 30% of the bill, and Judy paid 35% of the bill. Written in decimal form, what percent of the bill did Lynn pay

Answer 1

Let X be the total bill amount.

Jake paid 30% of the bill, so he paid 0.30X.
Judy paid 35% of the bill, so she paid 0.35X.

Together, they paid 0.30X + 0.35X = 0.65X of the bill.

Since the total bill is X, Lynn paid 100% - 65% = 35% of the bill in decimal form.

Therefore, Lynn paid 0.35X of the bill.
