Question

A store buys a jackets for $20.00 and sells it for 80% more than that what is the selling price of the jacket

Answer 1

Answer:

$36

Step-by-step explanation:

What we know: The jacket is marked up by 80% of the jacket. The store is now selling the jacket for 180% of what they bought it for.

Set up problem:    x        180%

                            ___ = ____

                           $20     100%

What do the numbers mean when set up like this(referring to problem set up): We know that $20 is the original price of the jacket. So $20 is 100% of the jacket(if that makes sense). Markup is 80% because "sells it for 80% more" . So it goes on top.

Solving the Problem#1:  180 x 20 = 3600

Solving the Problem#2: 3600/1000= $36

Checking My Math: What is 80% of $20. Let's divide $20 into 4 parts.  

$4 + $4 + $4 + $4 + $4 =20

$4 is 20% of 20

$8 is 40% of 20

$12 is 60% of 20

$16 is 80% of 20

$20 is 100% of 20

Final Answer: $36 is the selling price of the jacket

Note: I used a scientific calculator for some calculations.

Answer 2

Answer:

$36

Step-by-step explanation:

1. in the beginning $20 is %100 so divide 20 by 100                                              .
2. you'll get .2 but to make this simple you'll want %10 so multiply .2 times 10 and you get 2                                                                                                         .
3. now that 2 is %10 and you want %80 you multiply 2 8 times (or add it 8 times) because %10 times 8 = %80 so 2 times 8 = 16                                             .
4. now that you have the %80 you want to add it to the %100 because they sold it for %80 then the price they bought if for (you get %180)                                                     .
5. then you add the $20 to the $16 because that is what each percent equals (you get $36)
