A chair's regular price is $349. It is on clearance for 30% off, and a customer uses a 15% off coupon after that. What is the fi
rusak2 [61]

Answer:

$207.66

Step-by-step explanation:

Regular price = $349

clearance price = 30% of $349

= 0.03 * 349 = $104.7

therefore new price = $349 - $104.7 = $244.3 ( 70% of original price )

A customer using a 15% off coupon then the price would be

= ( 100% - 15%) ( 70% of $349 )

= 85% ( 70% of original price )

= 0.85 * $244.3 = $207.66 ( final cost of chair before sales tax )

sales tax is a tax been paid by the buyer on purchased item and the buyer purchasing the item after applying his coupon means that he would pay sales tax on the final price at which he bought the item and not the original price of the item.

Help me with question 1 please
GrogVix [38]

Answer:

DB = 6

Step-by-step explanation:

See the attached figure to the question.

Since O is the center of the given circle, so AB and CD are diameters of the circle.

Hence, AO = CO = OD = OB = radius of the circle = 6

In Δ OAC, we have AO = OC. Hence, ∠ A = ∠C = 60° {Given that ∠OAC = 60°}

So, ∠ AOC will automatically become 60°. {As the sum of all the angles of a triangle is 180°}

So, Δ AOC is equilateral triangle.

Now, ∠ AOC = ∠ BOD = 60°  {Since, they are vertically opposite angles}

Now, in Δ BOD, we have DO = OB. Hence, ∠ D = ∠ B = 60° {As the sum of all the angles of a triangle is 180°}

So, Δ BOD is also an equilateral triangle.

So, DB = BO = DO = 6. (Answer)
