O Reality Check ✔ Riley and Finley found their dream home! While attending graduate school, Riley works as a laboratory assistant and receives $20/hr. His husband, Finley, works as a banker and receives $17/hr. They calculated with their combined 115 hours worked, their income would meet the $2150 rent. Calculate the exact number of hours each one. works. Part 1: Application/Problem Solving (Two Systems of Equations) Directions: There are two ways to assign variables for this problem. To receive full credit, you must demonstrate both methods (in other words, you must solve this problem in two different ways). a) One way is to use "r" and "f" to stand for Riley's hours and Finley's hours worked, respectively. b) The other way is to let "r" and "f" stand for Riley's earnings and Finley's earnings, respectively. - 2150

Pedro and Rebecca were trying to solve the equation: 0.1x^2 - 0.7x + 1.2 = 0 Pedro said, “I can multiply the entire equation by 10 and then factor. Then I can solve using the zero product property.” Rebecca said, “I'll solve using the quadratic formula with a = 0.1 1, b = -0.7 and c = 1.2" WHOs Strategy works? A - Only Pedro's B - Only Rebecca's C - Both D - Neither
