Question

Ji min's grandmother asked him to pick up some ginger on his way home .He knows that she wants to get 2 meals(4oz/ meal)out of it and it costs $2.99 per root. how much will he spend if each root is approximately 6 oz?

Answer 1

Since 1 meal is equivalent to 4oz, then 2 meals are equivalent to 8oz (4*2=8).

Now, one root (6oz) cost $2.99 and we need 8oz, then Ji-min must buy 2 roots because he cant buy parts of the root, that is

`2.99\cdot2=5.98`

that is, Jim will spend $5.98 approximately.
