Answer 2

Answer:

The answer is 9.75

Step-by-step explanation:

First, convert the fraction of the pizza that Sully and Diane ate to percents to simplify the calculation.  Next, subtract the percentages of the pizza that Sully, Emma, and Diane ate from 100% to find the percentage of the pizza that Wayne ate.  Finally, multiply the percentage of the pizza that Wayne ate with the cost of the pizza, $19.50, to know, how much he should pay.

Therefore, Wayne should pay $9.75.
