Question 1104050
.
<pre>
It follows directly from the condition that 44-18 = 26 gallons of fuel weight 2286-2117 = 169 pounds.


Hence, 1 gallon of fuel weights {{{169/26}}} = 6.5 pounds.


Then 4 = 48-44 gallons weight 4*6.5 = 26 pounds,  


and the answer to the problem's question is 2286 + 26 = 2312 pounds.

All these calculations you can perform MENTALLY, so this problem is for MENTAL solution.
