The table gives the different combinations of stamps Karl has
the first option says that
a. The total number of stamps is 25.
according to this the addition of stamps for each combination should be 25
1st combination is 18 + 17 = 35
therefore this statement is wrong as the addition of stamps is 35 stamps
b. The total value of the stamps is $18.75.
lets check the first combination
18 x $ 0.45 + 17 x $ 0.65 = 8.1 + 11.05 = $19.15
so this statement too is wrong
c. The total number of stamps is 35.
as calculated above we know that the sum of the stamps in the first combination is 35
so lets check for the other combinations
20 + 15 = 35
22 + 13 = 35
25 + 10 = 35
so the answer is 35
this statement is correct
d.The total value of the stamps is $19.15
lets check the value for the third combination
22 x 0.45 + 13 x 0.65 = 9.9 + 8.45 = $18.35
this value isnt equal to $ 19.15
therefore this statement too is wrong
correct answer is C
