Bike store owner marks up the wholesale cost of all of the bikes they sell by 25%. 1. The owner purchased a bike for $120 (wholesale price). How much will he sell it for in his store?

$150

Step-by-step explanation:

Given data

Mark up =25%

cost price= $120

Required

The selling price

Applying the following expression we can solve for the selling price

Mark up = selling -cost/cost *100

substitute

let the selling price be x

25= (x- 120)/120 *100

cross multiply

25*120= (x-120)*100

3000= 100x-12000

3000+12000=100x

15000= 100x

divide both sides by 100

x= 15000/100

x=150

Hence the selling price is $150

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
