Bri and Ali are the owners of Forever Nails. Bris work day is 7 hours and Mables work day is 5 hours. Bri and Ali each work 35 hours per week. On Monday, Bri has 13 clients in 7 hours and Ali has 11 clients in 5 hours. They each earn 14.25 per client. Assuming that for the rest of the week Bri and Ali have the same number of clients per workday as they did on Monday, what will be the difference between their weekly earnings?

Ryan boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rotates at a constant angular speed of 6.5 radians per minute and has a radius of 30 feet. The center of the Ferris wheel is 36 feet above the ground. Let t represent the number of minutes since the Ferris wheel started rotating. a. Write an expression (in terms of t) to represent the varying number of radians 0 Cody has swept out since the ride started.b. Write an expression (in terms of t) to represent Cody's height (in feet) above the center of the Ferris wheel. c. Write an expression (in terms of t) to represent Cody's height (in feet) above the ground.
