The total amount he should pay is $69.6
20% of 58 is 11.6
11.6+58=69.6
1) 129.48 lbs : Multiply 156 by 0.17 to get 26.52, then 156 by 26.52 to get 129.48.
2) 1.96 : take 166.52 and divide that by 85. You will get 1.9590... and a lot of other crazy numbers. Round it to the nearest cent, you get 1.96.
3) 0.93 minutes : the faster time is 9.97 and the slowest is 10.9, subtract that and get 0.93.
4) 20.75 : add the prices up all together and you get 20.75
5) 18.32
6) 16.754
7) 56.44
8) I can't see the sign
9) 161.7
10) 737.49
11) 250
12) 405
13) 54.67
