If y varies directly with x, it means that the ratio of y to x is constant. We can set up a proportion using the given information:
y1 / x1 = y2 / x2
where y1 = 94, x1 = 47, x2 = 28, and we want to find y2.
Substituting these values into the proportion, we get:
94 / 47 = y2 / 28
To solve for y2, we can cross multiply and divide:
(94 * 28) / 47 = y2
y2 ≈ 56
So, when x = 28, y ≈ 56.
