Kayla is working two summer jobs, making \$10 per hour lifeguarding and \$21 per hour tutoring. Last week Kayla worked 4 times as many hours tutoring as she worked lifeguarding and earned a total of \( \$ 188 \). Write a system of equations that could be used to determine the number of hours Kayla worked lifeguarding last week and the number of hours she worked tutoring last week. Define the variables that you use to write the system. Answer attempt 1 out of 2

The Deep Dive
Let \( x \) be the number of hours Kayla worked lifeguarding, and let \( y \) be the number of hours she worked tutoring. We know from the problem that she worked 4 times as many hours tutoring as lifeguarding, so we can express this relationship as \( y = 4x \). Next, we consider her earnings. For lifeguarding, at \$10 per hour, she earns \( 10x \), and for tutoring, at \$21 per hour, she earns \( 21y \). The total earnings is given as \$188, which leads us to the equation \( 10x + 21y = 188 \). So, the system of equations is: 1. \( y = 4x \) 2. \( 10x + 21y = 188 \)
