Step-by-step explanation:
Circumference of the Circle with radius 4. =2πr=2π×4. Central angle that intercepts arc of length 10.8 =10.82π×4×2π =10.8 4
3x - 11 = -1x -75
3x = -1x -75 +11
3x + 1x = -75 + 11
4x = -64
x = -64/4
x = -16

Answer:
If you paid $22.26 after the discount and tax then 30% is 0.30 and 30% OFF is 1-0.30=0.70
Tax is 6% or 0.06 and along with the initial is 1+0.06=1.06 so P is original price in P×0.70×1.06=22.26
P×0.742=22.26
P=$30 was the original price
