Exercises 33 and 34 refer to the following situation: Jackie, Karla, and Lori are planning to divide the half vegetarian—half meatball foot-long sub sandwich shown in Fig. 3-22 among themselves using the lone- divider method. Jackie likes the meatball and vegetarian parts equally well; Karla is a strict vegetarian and does not eat meat at all; Lori likes the meatball part twice as much as the vegetarian part. (Assume that when the sandwich is cut, the cuts are always made perpendicular to the length of the sandwich. You can describe different shares of the sandwich using the ruler and interval notation—for example,
Figure 3-22
Suppose that Jackie is the divider.
a. Describe how Jackie should cut the sandwich into three shares. Label the three shares
b. Which of the three shares are fair shares to Karla?
c. Which of the three shares are fair shares to Lori?
d. Find three different fair divisions of the sandwich.

- Scenario 2: In the bathroom, the homeowners wish to install subway tile around the tub. The tile will be placed above the tub on the three sides that are enclosed. The bathroom has a 9-foot ceiling height and the tub is 60 inches long by 32 inches wide by 19 inches high. The tile the homeowners have selected is 3 inches by 12 inches and is sold by the box. Each box costs $34.99 and contains 22 tiles. The supplier provides free delivery and recommends purchasing a minimum of 10% overage. Question 6: Find the total cost for the tile, including sales tax.arrow_forward1) A Starbuck's store sells coffee in three sizes: a 12-oz tall, a 16-oz grande, and a 20-oz venti. A tall coffee sells for $1.75, a grande for $1.95 and a venti for $2.25. One morning Ethan served 50 coffees for a total of $98.70. He made the coffee in 80-oz batches and used exactly 10 of the batches during the morning. How many of each size coffee did he sell?
