Q. w=3.1+2lThe weight, w, in ounces, of a glass soda bottle design with a side length of l inches is given by the equation. By how many ounces does the weight of the bottle increase for every inch of increase in the side length?Choose 1 answer:(A) 0.5(B) 2(C) 3.1(D) 3.6
Analyze Equation: Analyze the given equation for the weight of the glass soda bottle.The equation is w=3.1+2l. This equation shows that the weight (w) is a function of the side length (l). To find out how much the weight increases for every inch of increase in side length, we need to look at the coefficient of l in the equation.
Identify Coefficient: Identify the coefficient of l in the equation.The coefficient of l is the number in front of l that represents how much w changes when l changes. In the equation w=3.1+2l, the coefficient of l is 21.
Interpret Coefficient: Interpret the coefficient of l in terms of the weight increase.The coefficient of 21 means that for every unit increase in l, the weight w increases by 21 of that unit. Since l is measured in inches, this means that for every inch of increase in the side length, the weight of the bottle increases by 21 ounce.
Match with Options: Match the result with the given options.The result from Step 3 is 21 ounce, which is not explicitly listed in the options. However, 21 can be expressed as 0.5, so the correct answer is (A) 0.5.
