Sunny earns $12
per hour delivering cakes. she worked for x
hours this week. unfortunately, she was charged $15
for a late delivery on tuesday.
how much money did sunny earn this week?

12x-15

Step-by-step explanation:

Let

x ---> total hours worked this week

we know that

To find out how much money Sunny earned this week , multiply the total hours worked by the rate of $12 per hour and subtract $15 for a late delivery

so

12x-15

< 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
