n+d=200 = n=200-d
0.05n+0.1d=$14.00
0.05(200-d)+0.1d=$14.00
10-0.05d+0.1d=$14.00
10+0.05d=$14.00
-10 -10
0.05d=$4.00
0.05d/0.05=$4.00/0.05
d=80

Step-by-step explanation:
If one person buys each one of the items. It would cost 1.50 + 3 + 2.50, which equals $7. If P is the amount of people that buy each one of the items then the total for them all would be P times 7. Therefore, the answer is 7P.
Answer:
The answer is 16 hours
Step-by-step explanation:
The Reason why it is 16 hours is simply because it says in the question
"The moon is around 239,000 miles from Earth. How many hours would it take a rocket that can travel at 250 MILES PER MINUTE to travel to the moon? Round to the nearest hour.
"
So, turn 16 hours into minutes, 16 X 60 = 960 X 250 miles per min = 240,000, miles there you go! the answer is B!
