kelly works at her own nail salon. today, she did 12 manicures and received $60.00 overall in tips.

if x represents the cost of each manicure, which of the following equations can be used to find the total amount of money she earned, including tips, for her nail salon today?
a. y = 12(x + 60)
b. y = 60(x + 12)
c. y = 60x + 12
d. y = 12x + 60

The correct answer is Choice D.

Step-by-step explanation: The correct answer is choice D.

Y = the total amount money that Kelly earned

X = the cost of each manicure

So, in choice D, the total amount that Kelly earned equals 12 times the cost of the manicure plus the 60 in tips that she received for the day.

< 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
