The price of a dress is Reduced 60% when the dress still does not sell it is reduced by 60% of the price if the price of the dress after both reductions is $80 what was the original price

$500

Step-by-step explanation:

let x = price of the dress before reductions

If the price is reduced by 60%, the price would be (100% - 60%) = 40%

Price after first reduction=  0.4x

Price after second reduction = 0.4(0.4x)

0.16x = $80

Divide both sides by 0.16

x = $500

< 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
