Answer:
74 Bolts
Step-by-step explanation:
First find how many bolts he had to start with:
7 x 11 = 77
Then simply subtract to find out how many he used:
77 - 3 = 74
I believe that the correct answer would be 74
you multiply 7*11 which equals 77 and then subtract 3 from the answer which gives us 74
