To find the slope, use the rise/run technique with rise as the difference in y-coordinates and run as the difference in x-coordinates. So, the rise is 6 units and the run is 3 units in this situation. Now simply put it as a fraction: 6/3, which can be simplified to 2/1, or 2.
If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way
Answer:
It would be 6
Step-by-step explanation:
After 6 months, ammount left to pay = $1,840.34
On the seventh month, he payed of the debt with the interest (for one month).
Amount paid off at the seventh month = 1840.34(1 + 0.09/12) = 1840.34(1.0075) = 1854.14
Amount to have paid in the remaining 6 months = 314.83 x 6 = 1888.98
Amount saved = 1888.98 - 1854.14 = $34.84
Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.
