Answer:
I think 10.5 would be the unit price and 10lbs of potatoes and 2lbs of tomatoes would cost less
Step-by-step explanation:
since tomatoes cost 2 times more I decided to act as he only bought potatoes and in that case he would have bought 22lbs of potatoes so I divided 16.50 by 22 and got .75 then I multiplied it by 10 and got 7.5 as well as multiplied .75 by two to get the price of the tomatoes then I added 7.5+3 to get 10.5
