Answer:
17.50
Step-by-step explanation:
you really don't need to know the tax amount.
20% of x = 3.50
(20/100) x = 3.50 Divide top and bottom of the left number by 20
(20÷20) / (100÷20) * x = 3.50
(1/5) x = 3.50 Multiply both sides by 5
x = 3.50 * 5
x = 17.50

The 2nd choice is correct
Step-by-step explanation:
Answer:
y = x + 3
Step-by-step explanation:
I'm assuming that you are asking for a line perpendicular to
3x + 3y = 3 and going through (-1, 2)
first find the slope of the line
3y = -3x + 3
y = -1x + 1, the slope is -1 so the perpendicular slope is 1
y = mx + b
2 = 1(-1) + b
3 = b
y = x + 3
