Answer:
let x =the original price
then 116x/100=$39.32
116x=100×39.32
116x=3932
divide both sides by 116
116x/116=3932/116
x=33.89655
(2dp)
x=33.90

Therefore , by Quadratic formula , , values of x are . None of mentioned options are correct according to question!
Answer:
The circle length is 90*pi which should be 3.14
So the circle length is 282.6
The central angle is 90 degree which is 1/4 part of 360 degree
From the theory of arc, the arc length should also be 1/4 part of circle length.
So the answer should be 1/4 * 282.6 = 70.65
Becasue it should be to the nearest tenth, so the answer should be 70.7
