Final answer:
When y = 20, x = ___? What is the value of y when x is 2%?
The answer is b) 0.04.
Step-by-step explanation:
The relationship between y and x, where y varies directly with x, is expressed as y = kx, where k is the constant of variation. When y = 20, to find x, we rearrange the equation as x = y/k. However, without the specific value of k, we cannot determine x directly.
Now, when x is 2%, this implies x = 0.02 (as a decimal). Since y varies directly with x, we can use the equation y = kx. To find y when x is 0.02, we substitute x = 0.02 into the equation. However, we still require the constant of variation, k, to solve for y accurately.
The options provided don't include the constant of variation (k) explicitly, making it impossible to solve for y precisely in this scenario. Instead, the question seems to confuse the percentage value of x (2%) with an actual numerical value. This confusion between a percentage and a numerical value makes it challenging to determine the exact value of y without the constant of variation, which isn't provided.
Therefore, the answer in the given options closest to the numerical value x = 0.02 (as a decimal) is option b) 0.04, but it doesn't accurately solve for y at x = 0.02 due to the absence of the constant of variation (k) or a specific value for x when y equals 20.
