Question

a certain chololate bar costs 35 pesos per pieces. however, if you buy more than 10 pieces, they will be marked down to a prices of 32 pesos per piece. use a piecewise function to represent the cost in terms of the number of chocolate bars bought.​

Answer 1

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
