Huang has a coupon that gives him 20% off all items purchased. he buys 3 shirts that each cost the same amount, and he pays with a $100 bill. which expression represents the amount of change huang should receive? check all that apply. 100 – (0.2(3x)) 100 – (0.8(3x)) 100 – (1 – 0.2)(3x) (100 – 1 – 0.2)(x + x + x) 100 – (0.8x + 0.8x + 0.8x)

2nd, 3rd and 5th options are correct choices.

Step-by-step explanation:  

We are told that Huang has a coupon that gives him 20% off all items purchased. He buys 3 shirts that each cost the same amount, and he pays with a $100 bill.  

Let x be the price of each shirt, therefore, price of 3 shirts will be 3x.

Using coupon he will get 20% off on 3 shirts, which means that he will pay 80% of 3x.    

Now let us subtract price of 3 shirts from $100 to find the amount Huang will receive as change.

Now let us see which of the given expression matches with our expression.

1.

In our 1st expression 20% of 3x is being subtracted from 100, while amount that Huang will spent on purchasing 3 shirts is 80% of 3x, therefore, 1st expression is not correct.  

2.

We can see that 2nd expression is same as our expression, therefore, 2nd option is the correct choice.

3.

Upon subtracting 0.2 from 1 our expression will simplify as:

Therefore, 3rd option is the correct choice.

4.  

Upon simplifying our expression we will get,

We can see that expression is not matching with our expression, therefore, 4th option is not correct.

5.

Upon factoring out 0.8 from our expression we will get,

Therefore, our 5th option is also a correct choice.

i can you with this sweetie!
