To find the sales tax from total bill, you would divide the total amount by "1 + the sales tax rate" (i.e., If the sales tax is 5%, divide the total amount by 1.05."
Soooo....
194.25 / 1.05 = 183.25**
** Now take that total and subtract it from the full total amount of 194.25.
194.25 - 183.25 = $11.00**
** This total is the amount of sales tax charged.**
Flipping a graph keeps the figures size the same, so it isn't A. Flipping it doesn't rotate the angles either(R is equal to R', S to S' etc.), so the answer is B.
