PLEASE SOMEBODY HELP ME!!!!!!I can mark your brainliastSolve Question 1

Answer 1

Answer:

$c(z)=0.20(z-1)+0.46$

Explanation:

Given;

Cost of mailing a letter weighing up to 1 oz = $0.46

Cost per ounce for each for additional ounce = $0.20

So the function that would determine the cost, c(z), of mailing a letter weighing z ounces is an integer greater than 1 can be found as seen below;

$c(z)=0.20(z-1)+0.46$
