Ozzie has a coupon for 5% off any purchase in his favorite bakery. when ozzie stops to buy some cookies, he discovers that all cookies are on sale for 15% off the regular price. the cookies are regularly $5.89 per dozen. if ozzie uses his coupon and pays 7% sales tax, how much does he pay for two dozen cookies?

Answer-

He needs to pay $10.17 for two dozen of cookies.

Solution-

Regular price of cookies = $5.89 per dozen.

Ozzie bought 2 dozens of cookies.

So, the regular price of 2 dozen = 2×5.89 = $11.78

But, all cookies are on sale for 15% off the regular price.

New price of 2 dozen of cookies will be,

But, Ozzie applies a 5% off coupon, so new price will be,

Now, the 7% sales tax will be levied on $9.50

So, the net amount that Ozzie needs to pay is,

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
