The unit price for sninach is 3.2 cents per ounce at that price how much would 1 pound of spanach cost ( round off the answer to the nearest cent

Ok so...

1 ounce is 3.2

There are 16 ounces in 1 pound

3.2 * 16

51.2

so the spinach would cost 51 cents  

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
