Question

Three students performed a science experiment using salt and a beaker. The beaker contained 530.2 grams of salt before the experiment started. During the experiment, each of the 3 students removed 47.36 grams of salt from the beaker. How much salt in grams was left in the beaker at the end of the experiment

Answer 1

Answer:

388.12 grams

Step-by-step explanation:

There is a total of 530.2 grams to begin with.

Each student removes 47.36 grams; since there are 3 students, this means that

47.36(3) = 142.08 grams removed.

This leaves us with

530.2-142.08 = 388.12 grams.

Answer 2

Assuming  each of the 3 students removed 47.36 grams of salt from the beaker. The amount of salt in grams left in the beaker at the end of the experiment is: 388.12 grams.

Number of grams of salt left

First step

Number of grams of salt deducted

Number of grams=47.36 grams ×3

Number of grams= 142.08 grams

Second step

Number of grams of salt left=530.2 grams-142.08 grams

Number of grams of salt left = 388.12 grams

Inconclusion the amount of salt in grams left in the beaker at the end of the experiment is: 388.12 grams.
