Please help. Really important At what percent above the cost price must an article be marked so as to gain 33% after allowing a customer a discount of 5%.

Step-by-step explanation:

x=costprice+profit+discount

Where profit is 33% of cost price and discount is 5% of marked price.

x=100+33+5x/100

x=133+x/20

x−x/20=133

19x/20=133

x=140

Cross check:

5% of 140 is 7 (discount). Price after discount is 133. And profit over cost price is 33, (133- 100) which is 33% of the cost price.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
