Alocal newspaper charges $18 for the first 3 lines of a want ad, and then $6.50 for each additional line. express the cost of an x-line ad, c(x), as a piecewise function. unit 5 financial algebra

c(x) =  

Step-by-step explanation:

Charges are :-

$ 18 for the first three lines of the add and $6.50 for each additional line

Thus,

for x ≤ 3 , cost will be c(x) = 18x

and if x > 3 , cost for the first 3 lines will be 18×3 = 54 dollars and then cost will increase by $6.50 for each additional line.

Thus c(x) = 54 + 6.5(x - 3)

So, the piecewise defined function c(x) can be represented by :-

c(x) =  

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
