First you need to make a multiplier:
1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
You would have to use this equation : y2-y1/x2-x1 = slope
So it would be -13 +3/6-2= -10/4
Simplify it and you get : -5/2
Slope is -5/2
X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
Answer:
eight hundred seventy-five thousand six hundred eighty-seven
