Answer:
55998000
Step-by-step explanation:
When you take 5 time 3 you get 15
Then you take 15 and times that by 17 and get 225
then you take that and multiply that to 200 and get 5100
Finally you multiply 5100 to 1098 and get 5598000
The slope, or gradient, of the line is 6/-3 which is -2. The gradient is -2.
To find the original amount, you divide the product by the percentage.
112.79 / 0.15 ≈ 751.933 (the 3's repeat infinitely).
To check your answer, multiply 751.933 by 0.15.
751.933 * 0.15 = 112.78995 ≈ 112.79
