Levi was given the following math problem: Given the function g(x) = 19.60 + 1.74x what is the value of g(30)?

Here's his work to solve the problem:

30 = 19.60 + 1.74x

-19.60 -19.60

10.40 = 1.74x

1.74 1.74

5.977 = x

Levi's , Ashley, is trying to help Levi with his math skills. Help Ashley by: 1) identifying Levi's mistake and 2) determining the correct answer.

answer: options?

step-by-step explanation:

15 units use socratic

step-by-step explanation: 15 units

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.
