D=1.2*40

1.2 is the same as 120% (the same time PLUS 20% more), and the answer would be in minutes
D = Danika
Danika did homework for 48 minutes, btw

If you didn't know how long Ellen did homework for, it would be
D=1.2*E
where E=time ellen does her homework for

Danika spends 100% of the time Ellen does on homework, plus 20%. That means Danika spends 120% of what Ellen spends. If Ellen spends 40 minutes on homework, Danika spends 120% of 40. 120% as a decimal is 1.2

let d = Danika

1.2(40)=d
48=d

Danika spends 48 minutes on homework.

x=40+40(0.2). X is the time it takes Danika. 40 is how much time Ellen spends and 40(0.2) is the 20% time above the 40 minutes that Danika spends. I hope that helped.

40 (minutes) - 20%

40 X .20= 8

40-8+ 32

Danika spends 32 minutes on her homework
