At store A, 3 pounds of apples cost $12. At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples. The cost of apples at store C is shown in the graph.
What is the unit price of apples at store A? Explain how you found this unit price.
Try dividing 12 / 3.
So, it's saying 3 pounds of apples is 12 dollars. Now, we're trying to figure out how much each pound of apple costs. Let's set y=pounds and x= cost. (On this graph) Let me graph this question for you.
That's for Store A.), you can find the price per pound, using that graph.
wait whats the answer:?
Well, do you see how each time I buy a pound of apples, it cost four dollars? Look on this graph:
4 bucks
Exactly! $4.00 ~ Per Pound !
\[y=$4.00\] \[x=1~~Pound\] Placing that into the equation for Store B.) \[y=2x\] Based, on that it states, It's 2 dollars for one pound.
