Answer:

x = number of bar of chocolate

f(x) = 35x 0 < x ≤ 10

f(x) = 32x x > 10

How to use the piecewise function?

If x = 9 ⇒ Use the first function because 9 is ≤ 10

f(x) = 35x

f(9) = 35(9) = P 315.00

If x = 17 ⇒ Use teh second function because 17 > 10

f(x) = 32x

f(17) = 32 (17) = P 544.00
