5 x plus 7 y greater-than-or-equal-to 140
The first quadrant of a coordinate plane is shown with the x axis labeled Babysitting and the y axis labeled Lifeguard. A solid boundary line is graphed with a y intercept of 20 and an ax intercept of 28. Shading is above the boundary line. (7,15), (14, 10), and (0,20) are three possible solutions.
