Answer:
$782(Dylan) or $870(Lucy) you tell me
Step-by-step explanation:
Dylan
1000-80= 920
put this into fraction form like so
[tex]\frac{x}{y} = \frac{p}{100}[/tex] 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. [tex]\frac{x}{1000} =\frac{15}{100}[/tex] (1000· 15) ÷ 100= 150
2. 1000- 150=
3. 950-80=
$870
sorry if this was unbearably long.
