2t/5=8t/20 (both numbers multiplied by 4)
t/4=5t/20 (both numbers multiplied by 5)
3=60/20
⇒ 8t/20 - 5t/20= 60/20
3t/20=60/20
⇒3t=60
t=60:3
t=20
I hope you understand !

Answer:
11h + 15s = E
Step-by-step explanation:
E = total earnings
s = the amount of skis sold
h = how many hours she works
A=Annual amount=2000
i=annual interest=0.0205
n=number of years=3
Present value
=A((1+i)^n-1)/(i(1+i)^n)
=2000(1.0205^3-1)/(.0205(1.0205^3))
=5762.15
