Find the total cost of the pizza before tax.
15 × 8 = 120
Set up a proportion to find the tax. 7/100 = x/120
840 = 100x
Divide both sides by 100
Tax = $8.40
$120 + $8.40 = $128.40

Answer: 69.3 and 110.7 degrees
To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:
A/P = 1 + rt.
Next, isolate rt by subtracting 1 from both sides:
A/P - 1 = rt
Finally, divide both sides by t:
A/P - 1
----------- = r
This could be written in other formats, such as:
A - P
-------- = r

There's a theorem for this: the angle made by two intersecting secants of a circle has a measure equal to half the difference of the arcs the secants intercept. In this case,
<em>x</em> = (130° - 30°) / 2 = 50°
12+6/7n=-25n add 25n and subtract 12 on both sides
25 6/7n=-12 convert to improper fraction
181/7n=-12 multiply both sides by seven to clear the fraction
181n=-84 divide both sides by 181 to get your answer
