Answer: p= (-0.10)x + 31
Step-by-step explanation:
m is the slope, and we know that each time they need to drop $0.10 so that is our slope. For the b we just need to get $0.10 times 260 cards that need to sell and add 5 and we get 31. So, the equation is p= (-0.10)x + 31.
Thank you if you can give me the brainliest.
