Question 1195183
<br>
The weight is a linear function of the amount of fuel; the slope of 5.5 means each gallon of fuel adds 5.5 pounds to the weight.<br>
The difference between 47 gallons and 13 gallons is 34 gallons; at 5.5 pounds per gallon, that is 34(5.5) = 187 pounds.<br>
The weight with 47 gallons of fuel is 2258.5 pounds, so the weight with 13 gallons of fuel is 2258.5-187 = 2071.5.<br>
ANSWER: 2071.5 pounds<br>
