Multiply: (9-8i)(-6,-15i)

(9-8i)(-6,-15i) = -174 + 183 i

Step-by-step explanation:

Explanation:-

Given that  the complex numbers

                           (9-8i)(-6,-15i)

multiply           ( 9-8i ) ( -6 -15i)

               =  -54 - 9(-15 i) + 48 i +  120(i)²

               =   -54 + 135 i + 48 i - 120

              =    -174 + 183i

Final -

(9-8i)(-6,-15i) = -174 + 183 i

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