Question

Mr. Smith has a super-sized bag of Gummy Bears. He goes to eat from the bag of Gummy bears which has 300 Gummy Bears in it. Mr. Smith eats 20 Gummy Bears every 3 minutes. Write an equation to model the number of Gummy Bears in his bag.

Answer 1

Answer:

$\frac{20}{3} x=300$

Step-by-step explanation:

Given that the bag has 300 Gummy Bears and Mr.Smith eats 20 Gummy Bears every 3 minutes, then;

Lets assume x time taken to finish all Gummy Bears in the bag, then

Given in the question that

3 minutes =20 Gummy Bears

? minutes=300 gummy Bears

Perform cross-multiplication

$=\frac{300*3}{20} =45minutes$

This means after 45 minutes the bag of Gummy Bears will be empty.

The equation to model the number of Gummy Bears in the bag will be;

$\frac{20}{3} x=300$

Answer 2

Answer:

     $600-\frac{20}{3}\text{x}$

Step-by-step explanation:

Given: Mr. Smith has a super-sized bag of Gummy Bears. He goes to eat from the bag of Gummy bears which has 300 Gummy Bears in it. Mr. Smith eats 20 Gummy Bears every 3 minutes.

To Do: Write an equation to model the number of Gummy Bears in his bag.

Solution: Total Number of Gummy bears in Mr. Smith's super-sized bag =$300$

  Number of Gummy bears eaten by Mr. Smith in every 3 minutes = $20$

Number of Gummy bears eaten  by Mr. Smith in every in minutes= $\frac{20}{3}$

Now,

The number of Gummy bears in his bag after $\text{x}$ minutes is

                                         =$600-\frac{20}{3}\text{x}$

                     

The equation for number of gummy bears in Mr. Smith's bag after $\text{x}$ minutes is                

                                              $600-\frac{20}{3}\text{x}$
