q: in 2013 , the united states postal service charged $0.46 to mail a letter weighing up to 1 oz. and $0.20 per ounce for each additional ounce. which function would determine the cost, in dollars, c(z), of mailing a letter weighing x ounces where z is an integer greater than 1 ?

possible answers: a. c(z) = 0.46 + 0.20, b. c(z) = 0.20z + 0.46, c. c(z) = 0.46( z - 1 ) + 0.20, d. c(z) = 0.20 (z - 1 ) +0.46

B

Step-by-step explanation:

0.20 represents the cost per ounce

“Z” represent the number of additional ounces

0.46 is the fee that is added on for the first ounce when mailing the letter

8121 because

130,000 divided by 16 is 8121

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:
