Answer

Explanation:

Step1: Calculate total number of stamps for each row

For the first row: (18 + 17=35) For the second row: (20+15 = 35) For the third row: (22 + 13=35) For the fourth row: (25+10=35)

Step2: Calculate total value of stamps (in cents) for each row

First row: (18\times45+17\times65=810 + 1105=1915) cents ((1915\div100=$19.15)) Second row: (20\times45+15\times65=900+975 = 1875) cents ((1875\div100=$18.75)) Third row: (22\times45+13\times65=990+845=1835) cents ((1835\div100=$18.35)) Fourth row: (25\times45+10\times65=1125+650 = 1775) cents ((1775\div100=$17.75))

Answer:

The total number of stamps is 35.
