Jack plans to buy 2.25 pounds of coleslaw at $2.80 per pound. how much will he have to pay for that?

I think the answer is $6.30 , because you have to add. So 2.80 multiple by 2 would be 5.6 and after that you divide 2.80 by 4 since .25 it's a quarter of the whole so that gives you 6.3.

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
