The owner increases the sale price by the same percent that you found in part a when she buys jackets for $45 and sells them. How many jackets must the owner buy for the total jacket sales to be
at least $250? Explain your answer.

divde and youll get your answer 45 dived by 250 = 0.18 but just put 18

if this is really you s much. i only have 3 points left and i have 2 questions to ask

< 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
