Fish sells for $4.86 per lb. You buy 2 pieces which cost a total of $12.15. How many lbs. of fish do you buy?

Question

Need answer ASAP please! Thanks!

Answer 1

The price you pay is the product of unit price ($ per lb.) and # of lbs.

 

We know that $4.86 = unit price of the kind of fish that you bought.  Let w = weight (in lbs.) of your purchase.

 

Then $12.15 = $4.86 w

 

You solve this equation for w by dividing both sides by 4.86.
