The tax rate as a percent, r, charged on an item can be determined using the formula startfraction c over p endfraction minus 1 equals r. – 1 = r, where c is the final cost of the item and p is the price of the item before tax. louise rewrites the equation to solve for the final cost of the item: c = p(1 + ). what is the final cost of a $40 item after an 8% tax is applied?

$43.2

Step-by-step explanation:

Given Formula :

r is in decimals

Where c is the final cost of the item

p is the price of the item before tax.

Now we are supposed to find the final cost of a $40 item after an 8% tax is applied

So, r = 8% = 0.08

p = $40

Substitute the values in the formula :

So,

Hence  the final cost of a $40 item after an 8% tax is applied is $43.2

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
