20 . a certain church bell rings the bell twice at half past the hour and 4 times at the hour plus an additional number of rings equal to what ever time it is . how many rings will the clock make from 6 : 20 in the morning to 09 : 50 in the morning ?
unless i understood the problem correctly , i get 58 @ 6 : 30 - 2 @ 7 - 4 + 7 = 11 @ 7 : 30 - 2 @ 8 - 12 @ 8 : 30 - 2 @ 9 - 13 @ 9 : 30 - 2 totals to a = 44
add(add(multiply(4, const_2), multiply(4, 4)), add(add(add(const_3, const_4), add(const_4, const_1)), 6))
