If the salesperson sells “x” units of goods, then the pay is given by the linear equation y = 6x+120. a. Graph the equation labeling the x-intercept and y-intercept. b) what is the least amount of money that the salesperson will earn? c) . Show using the linear equation above what the salesperson’s weekly pay if 40 units are sold. d) use Desmos to determine the salesperson’s weekly pay if 20 units are sold. e) use Desmos to determine how many units must be sold in order to have a weekly pay of $600.arrow_forward
- A farmer plans to fence in a rectangular pasture adjacent to a river (see figure below). The pasture must contain 180000 square meters. No fencing is needed along the river. The Constraint is an area of 180000 square meters. Write an equation for the area in terms of x and y. This is called the secondary equation. 180000 = square meters (secondary);arrow_forwardPaying for college Rolf must earn 5040 for next semesters tuition. Assume he works x hours tutoring algebra at 14 per hour and y hours tutoring Spanish at 18 per hour and makes his goal. Write an equation expressing the relationship between x and y, and graph the equation. If Rolf tutors algebra for 180 hours, how long must he tutor Spanish?arrow_forward
