Mike is shopping for new cloths. He has a coupon for 20% off of his total purchase. His purchase price before the discount is $68. Let T represent the total cost after the discount. which equation can be written to model the scenario?
select all that apply
A.69-0.2(68)=T
B.68-.20=T
C.68-20=T
D.0.8(68)=T
0.2(68)=T

Answer 1

The correct equation to represent the total cost after applying a 20% discount on a $68 purchase is 0.8(68) = T. This reflects paying 80% of the original price after the discount.

Step-by-step explanation:

Mike is using a coupon for 20% off his total purchase, which is $68. To represent the total cost after the discount with a variable T, we want to subtract the discount from the original price:

The 20% discount of the original price is calculated as 0.2 multiplied by $68, which equal to $13.6. Therefore, the equation representing the total cost after the discount (T) is obtained by subtracting the discount from the original price.

Option A: 69 - 0.2(68) = T is incorrect due to the wrong original price (should be 68, not 69).

Option B: 68 - .20 = T is incorrect because it subtracts 20 cents, not 20 percent.

Option C: 68 - 20 = T is incorrect because it subtracts $20, not 20 percent.

Option D: 0.8(68) = T is the correct representation since taking 20% off is the same as paying 80% of the original price.

The last option: 0.2(68) = T gives us the amount of the discount, not the total cost after the discount.

Answer 2

I'm pretty sure it's d

Step-by-step explanation:

20 percent is the discount. Everything has 100%, so if you take away 20% of the 68$ you will get only the amount of the discount; however, we are looking for the price after the discount. Since 20% is the discount, then perhaps 80% is the cost after the discount is used; therefore, if you multiply .8 which is equal to 80% to 68, you will get the cost after the discount. The answer would be .8(68)=T
