Answer:

y = 225

Step-by-step explanation:

since y and x are directly proportional the equation relating them is

y = kx ← k is the constant of proportionality

to find k use the given condition y = 288 when x = 32

k = \frac{y}{x} = \frac{288}{32} = 9

y = 9x ← is the equation of proportionality

when x = 25, then

y = 9 × 25 = 225

lisabon 2012 [21]

Answer:

Step-by-step explanation:

First find the markup

markup = 16 * 400%
