Michelle, Lori, and Patti buy lunch together. The total bill was $45. If Michelle pays 35% of the total bill and Lori pays 48% of the total bill, how much of the total bill will Patti pay?

17% of the bill

Step-by-step explanation:

Well to find the answer to this question we first have to add 35 + 48 to get the total percent of the bill that Michelle and Lori paid.

35 + 48 = 83%

now that we know the percent of the bill that Lori and Michelle are paying we have to subtract that amount by 100% to get the percent of the bill that Patti is paying.

100% - 83% = 17%
