$129.6
you do 100 times .08 and get 8 so 100 + 8 = 108
then you do 108 times .20 and get 21.6 so 108 + 21.6 = 129.6
Answer:
Option The graph will be a dashed line with a y-intercept of negative eight and a slope of three. The graph will be shaded above
the line
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line The equation of the dashed line is 
The slope of the dashed line is positive 
The y-intercept of the dashed line is -8
see the attached figure to better understand the problem
Turn the percentage into a decimal.
6% = 0.06
Multiply.
990 * 0.06 = $54.9 (sales tax)
Add.
990 + 54.9 = $1,049.40 (total price)
Best of Luck!
