A sheet metal company had 5 contracts last month. The contracts were worth $5600, $2800, $7450, 1900, and $8900. Materials, salaries and all other expenses last month totalled $23,750. What was the percentage of the profits

Step-by-step explanation:

Do percent Proportions

23,750           x                                        

     100

5

Cross multiply

23,750×100= 2375000

5×x= 5x

2375000÷5+

idk sorry

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

1 + (6 / x - 1)
