Question

If you have the following data about a bag of chips, about

how many chips are estimated to be in the bag?
Mass of Chips + Bag = 369 grams
Mass of 25 Chips = 45 grams
Mass of Bag ONLY = 28 grams
Approximately, how many chips are in the bag?

Answer 1

189 chips are estimated to be in the bag.

Explanation:

• Subtracting the mass

Mass of Chips = Mass of Chips + Bag - Mass of Bag

Mass of Chips = 369 g - 28 g

Mass of Chips = 341 g

• Dividing the mass

Mass of 1 Chip = Mass of 25 Chips / 25

Mass of 1 Chip = 45 g / 25

Mass of 1 Chip = 1.8 g

• Dividing the mass of chips in the bag by the mass of one chip

Number of Chips = Mass of Chips / Mass of 1 Chip

Number of Chips = 341 g / 1.8 g

Number of Chips ≈ 189
