Jim's science class is making slime from cornstarch and glue. Jim is helping pass out materials. He gives each student 80 grams of cornstarch from a 2-kilogram bucket. If Jim's class has a total of 21 students, how many grams of cornstarch will he have left?

Respuesta :

The total amount of corn starch left is 320 grams.

How to find the grams of corn starch left?

He gives each student 80 grams of corn starch from a 2-kilogram bucket.

Each students collected 80 grams of corn starch.

Therefore,

1 student = 80 grams of corn starch

His class has a total of 21 students.

Therefore,

total mass of corn starch distributed = 21 × 80

total mass of corn starch distributed = 1680 grams

The corn starch from the bucket = 2 kg

1kg = 1000 g

2kg = 2000g

Hence,

The corn starch from the bucket = 2000 grams

Finally,

amount in grams of corn starch left  = 2000 - 1680

amount in grams of corn starch left  = 320 grams.
