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 = [tex]\frac{y}{x}[/tex] = [tex]\frac{288}{32}[/tex] = 9
y = 9x ← is the equation of proportionality
when x = 25, then
y = 9 × 25 = 225
