Answer:
The price of one ear of corn is $0.70.
Step-by-step explanation:
This one is pretty simple since it asks for the price of just one ear of corn, so you just need to know the constant of proportionality. Since you were given a lot of information, pretty much all you have to do is divide y/x and that will give you k or also the constant. You can use the equation y=kx. So I did $1.40 divided by 2 and got $0.70. I did the same for the others (y/x) and got $0.70. But just keep in mind that if they were to ask for the price of 3 ears of corn, for example, you shouldn't just give them the constant. However, what you can do if multiply 3 (which is x in this case) with the constant ($0.70), you would get $2.10. But that's just for extra help.
I hope this helps
