George wants to borrow $30,000 to purchase a car. After looking at a monthly budget he realizes that all he can afford to pay per month is $350. The dealership is offering a 4.77% loan. When George hears how much interest he will pay over the life of the loan, he decides to cut back on his entertainment expenses and pay $400 per month. How much in interest will George save by paying an extra $50 per month? Hint: Round any loan length calculations to the nearest quarter of a year.

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.

d will be the best answer

okey so the slope is -3/5 and the y -intercept is 7/5
