(- d + e)(4e + d)
-d*4e - d^2 + 4e^2 + de
-d^2 - 3de + 4e^2

Answer:
$75 I think. Not 100% sure but like 95% sure :)
Check the picture below.
Make sure your calculator is in Degree mode.
8 people pull a 16 ton truck
we can make that a proportion
8:16
which can be reduced to
1:2
that means 1 person can pull 2 tons
to pull a 60 ton truck, you would have a proportion of
x: 60 = 1:2
cross multiply and you get
60 = 2x
x = 30
yes, you're right!
