loss) on the television sets?
Answer: A salesman bought 2 dozen television sets at $300 each. He sold two-thirds of them at a 25% profit but was forced to take a 30% loss on the rest. what was his total profit(or loss) on the television sets?
----
Original cost 24*300 = 7200
----
Profit: 0.25*(2/3)24*300 = 1200
---
Loss: 0.3*(1/3)24*300 = 720
----
Total profit = 1200-720 = $480
Step-by-step explanation:
y = 3x − 1
Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points)
Part B: What is the solution to the pair of equations? (4 points)
You didn't give any answers, but, I hope this will help you out a bit:
for example, if the air freshener sprays 3 times every 20 minutes,
here are our points:
(20,3), (40,6), (60,9), (80,12)
lets take the second and third point to find the slope.
3/40 would be the slope.
