Callie wants to buy a new pair of jeans that regularly costs $40. If the jeans are on sale
for 20% off, and sales tax is 7%, how much
will Callie pay for the jeans?

$34.24

Step-by-step explanation:

First step I'd do is find how much it costs after the discount, then, after find the total with tax because it's taxed after the discount.

So to find the discounted price you simply multiply the discount by the original price then subtract the discount from the price to get the discounted price.

So the discounted price without taxes is $32. Now to find the price with tax you do the same thing but instead of subtracting, you add it

So the total price Callie will pay for the jeans is exactly $34.24

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
