<u>Answer:</u>
He must sell 190 posters make a profit of $300.
<u>Explanation:
</u>
Given:
Base fee= $270
Fee for supplies= $2
Cost of poster=$5
To find:
The number of posters to be sold to get a profit of $300=?
Solution:
Let the number of posters sold be n.
Now, we know that,
profit = selling price – cost price
$ 300 = $ 5 for each poster – ( $ 270 base fee + $ 2 for each poster)
300 = 5 x n – (270 + 2 x n)
300 = 5n – 270 – 2n
5n – 2n = 300 + 270
3n = 570

n = 190
Answer:
B. 7.5 hours
Step-by-step explanation:
Assuming that both hoses fill at the same rate, then by simple proportion,
To raise the pool by 1 foot of water:
1 hose ---> takes 3 hours
2 hoses ----> fills twice as fast ---> will take half the time ---> 3/2 = 1.5 hrs
Hence with 2 hoses, it will take 1.5 hours to fill 1 foot of water.
to fill 5 feet of water, we will need 1.5 hours x 5 feet = 7.5 hours
