Answer:
106
Step-by-step explanation:
Sum of angles around a point = 360 degrees
Sum of given angles = 164+90 = 254
Thus, the value of x is the angles remaining from 254 to make 360
360-254 = 106
Hope this helps
Good luck
Answer:
a. $20.45
b. $24.55
c. $4.55
Step-by-step explanation:
In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.
we proceed as follows
Firstly, we want to find the cost price given the selling price and the mark up percentage.
mathematically;
profit =( selling price - cost price)/cost price * 100%
here our profit is 120% with the cost price being $45. we plug these values
120 = 45-cp/cp * 100%
120cp = 100(45-cp)
120cp = 4500 -100cp
220cp = 4500
cp = 4500/220 = $20.45
His profit is selling price - cost price = 45 - 20.45 = $24.55
His profit selling same shoe for $25 is 25-20.45 = $4.55
