Answer 1

D and E!!

Step-by-step explanation:

D - to find the percent mark up, you have to multiple the total by the percent (you write percents as decimals out of 100). then you would also have to add the total amount.

E - it is the same concept except also multiplying 400 by 1 before multiplying 400 by .32.

Hope this helps!!

Answer 2

3rd and 4th answer

Step-by-step explanation:

400 × 1.32

or

400 + 400×0.32

why ?

400 × 1.32 = 400 × (1 + 0.32) = 400×1 + 400×0.32 =

= 400 + 400×0.32

in general, this means that the price is 32% higher than the old 100% ($400). so, in total 132% compared to the old price.

therefore the 1.32 factor, which creates 132% out of 100%.
