Question

Katrina is making three batches of cookies for an upcoming picnic. She needs sugar for all three recipes;so she adds it to her grocery list. If her first batch of cookies requires 160 grams, her second batch needs 250 grams, and her third batch needs 180 grams, about how much sugar does she need? A) 550 g B) 600 g C) 650 g D) 700 g

Answer 1

B. 600g, Because she is going to need 570 over all so she wouldn't be able to use 550g because it isn't enough. C & D is just way to much sugar so you would need 600g which leaves an extra 30g of sugar.

Answer 2

So all you have to do is add all three batches of sugar together.
160+250+180
When I add up all three I get 590.
Are you sure the answer choices are correct when you typed them out?
