1) C. 100

a pentagon has 540 degrees 

130 + 130 + 90 + 90 + x = 540
440 + x = 540 
x = 100

2) C. 169

a hexagon has 720 degrees

151 + 135 + 115 + 75 + 75 + x = 720
551 + x = 720
x =169

My dinner at San Felipe cost $8.20 before tax and $9.96 after tax. What was the sales tax rate?
Aleonysh [2.5K]

Answer:

Sale tax rate = 21.46%

Step-by-step explanation:

Sale Tax % = ( Amount after sale tax - Original  cost) ÷ original × 100

Sale Tax % = ( $9.96 - $8.20) ÷ $8.20 × 100

Sale Tax % = $1.76 ÷ $8.20 × 100

Sale Tax % = .2146341463 × 100

 Sale Tax % = 21.46
