Devon is trying to find the unit price on a 6-pack of drinks on sale for $2.99.His sister says each drink would cost just over $2.00. Is she correct ,And how do you know? If she is not, how would Devon's sister find the correct price?
If we know that 6 things cost 2.99 and we want to know unit price we just have to divide 2.99 by 6. So 2.99:6=0.49$ - its the result. Now we can say that his sister is not correct, because price is different that 2$/unit.
