The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, i in dollars, of the item

The required expression would be .

Step-by-step explanation:

Since we have given that

Let the regular price of an item be 'p' dollars.

Discount % = 20%

So, Amount of discount would be

So, the expression represents the sale price would be

Hence, the required expression would be .

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
