Answer: a.
Step-by-step explanation:
46 is subtracted by n to get -21 so the equation is 46 - n = -21
Add n on both sides; 46 - n + n = -21 + n; 46 = -21 + n
Add 21 on both sides; 46 + 21 = -21 + n + 21; 67 = n
So n = 67
You would be able to stuff 247 envelopes because two 91's would be 1.3 hours then you add .2 hours which is 65 envelopes in that time.
