Anthony decided to buy two DVDs that were not included in the deal. His price before tax was $19.99. What was the cost of the two DVDs after the 8.25% tax was added?

Given:

Cost of 2 DVDs before tax = $19.99

Tax rate = 8.25%

To find:

The cost of 2 DVDs after the tax was added.

Solution:

We have,

Cost of 2 DVDs before tax = $19.99

Tax rate = 8.25%

So,

Tax = 8.25% of Cost of 2 DVDs before tax

Now,

Cost of 2 DVDs after tax = Cost of 2 DVDs before tax + Tax

                                         = $19.99 + $1.65

                                         = $21.64

Therefore, the cost of 2 DVDs after the tax is $21.64.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
