HELP PLS!! INCLUDE EXPLAINING THANK YOU

$782(Dylan) or $870(Lucy) you tell me

Step-by-step explanation:

Dylan

1000-80= 920

put this into fraction form like so

   y= new total(920)

               p= percent

then multiply on the diagonal and divide on the horizontal like so

(y·p) ÷ 100

then subtract the value you get from y

dylan spends

$782

Lucy

use the same process but in reverse

first calculate how much 15% of 1000 is then then take that value away with the 80$

so steps

1.  (1000· 15) ÷ 100= 150

2. 1000- 150=

3. 950-80=

$870

sorry if this was unbearably long.
