MCan you please explain more so I can give you the answer as a fraction
Answer:
Step-by-step explanation:
Looking at the graph we could locate the y intercept at point (0,-3) and we can locate another point (4,3) which also passes through the line. So using these coordinates we already know the the y-intercept as -3 but we need to find the slope to write it in slope intercept form.
To find the slope, we will need to find the difference in the y values and divide it by the difference in the x values.
(0,-3)
(4,3)
-3 - 3 = -6
0-4 = -4
-6 /-4 = 3/2 so now we know that the slope is 3 over 2
so we could write the equation as y = 3/2x -3
Answer:
The tax amount is 15.17$
The tax rate is 12.4%.
Step-by-step explanation:
First we subtract the cost from the selling price.
137.17 - 122 = 15.17
We have found the tax amount, now for the tax rate.
If tax rate is x, then
122 * x = 137.17
Divide both sides by 122 to get
x = 137.17/122 = 1.124, or .124.
Then convert into percentage by moving the decimal to the right 2 times.
.124 = 12.4%
Hope this helps you
