Let $x be the cost of each box of apples,

200x - 300 = 160x + 180

40 x = 480

x = 12

Each box of apples costs $12.

He used up $12 x 160 = $1920

He now have 50 x 160 = 8000 apples.

He sold 8000 - 95 apples which is 7905 apples.

He got $(7905 x .3) = 2371.5 Hope my mental calculation is correct.

Profit = 2371.5 - 1920 = $451.5

By the way I'd like to use array more though :P

I am going to provide the steps for the solving :D 

\(L+M = 1.74\\ L = M+0.16\\ (M+0.16)+M = 1.74\\ 2M + 0.16 = 1.74\\ M = \dfrac{1.74-0.16}{2}=0.79\\ L = 0.79 + 0.16 = 0.95\)

10000/8000

= 10/8

= 5/4

= 1 1/4

$ 1 1/4 for each question.

Give both of us $1.25? :D 

I saw the \(\boxed{\text{1 user composing an answer}\\\text{Melody}}\) box so I thought my answer was wrong. Thank you for saying that we are both correct XD.

This calculator is called 'web 2.0 calc'!! Welcome!! 

Oh oh oh my bad. Sorry

2x = 1234 84/99

x = 617 42/99 (instead of 617 44/99) = 617 14/33

y = 2000/3 - 20375/33 = (22000 - 20375)/33 = 1625/33 = 49 8/33

Sorry Guest who asked the question.

Why find the average speed? :)
