Math Problem Statement
Question content area top Part 1 The postal service of a country charges $ 0.34 postage for a letter weighing up to 1 ounce, plus $ 0.24 for each additional ounce up to 5 ounces. Letters weighing more than 5 ounces do not qualify for these rates. Question content area bottom Part 1 (a) Write a piecewise-defined function C for the postage charged for a letter weighing x ounces. Upper C left parenthesis x right parenthesis equals left brace Start 5 By 2 Matrix 1st Row 1st Column $ nothing 2nd Column if 0 less than x less than or equals 1 2nd Row 1st Column $ nothing 2nd Column if 1 less than x less than or equals 2 3rd Row 1st Column $ nothing 2nd Column if 2 less than x less than or equals 3 4st Row 1st Column $ nothing 2nd Column if 3 less than x less than or equals 4 5st Row 1st Column $ nothing 2nd Column if 4 less than x less than or equals 5 EndMatrix
