Question 1111735
.
<pre>
From the condition, the weight of 1 gallon of fuel is 


w = {{{(2387-2303)/(35-15)}}} = 4.2 pounds.


Now, to answer the question, we need to add the weight of (50-35) = 15 gallons of fuel to the weight of the plane 
carrying 35 gallons of fuel, 2303 pounds.


So, the answer is 2303 + 15*4.2 = 2366 pounds.
</pre>

<U>Answer</U>.  2366 pounds.


Solved.
