A dozen eggs cost 1.50$. How much will 18 eggs cost at the same rate?

$2.25

Step-by-step explanation:

A dozen = 12 eggs = $1.50

1 egg = 1.5 / 12 = 0.125

18 eggs = 0.125 * 18

             =  $2.25 = 1 1/2 dozen

< 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
