Mrs. baker paid $2.50 for 5 pounds of bannas. write an equation relating the cost c to the number of pounds p of bannas. how much would mrs. baker pay for 8 pounds of bannanas?

So, if she paid 2.50 for 5 pounds, how much would she pay for one pound? we divide by 5:

2.50/5=0.50

so one pound costs 0.50 dollars.

then for 8 pounds, she'd pay eight times this much, that is 4 dollars.
 

I'm not sure but i think it's 1670km/h
