Answer: He practiced for 40 more minutes.
Step-by-step explanation: Comparing Wendesday's time to Monday's. you subtract 50 from 90, giving you 40.
So we know that its $42 a day for Truck A, and its another $0.72 per mile, so we can use d for the number of days, and m for the number of miles:
Truck A: 42d+0.72m
We also know that Truck Company B charges $70 per day and an additional $0.12 a mile. Again, we can use d for the number of days and m for the number of miles:
Truck B: 70d+0.12m
Now if we start plugging in values, we will find when they cost the same. The rest is in the picture. Your answer is m≈47
I don't know. This seems tricky. But I do know that the probability would be 1 divided by the probability. So A and D is Incorrect. Theres never really a 50-50 chance with Locker doors so I'm gonna go with C.
I'm not guaranteed this is the answer. But I do Hope it helps. =)
