Please help.. this is so difficult.. The Martinez family ate at a restaurant.

The cost of the meal was $34.50.
The sales tax was 6% of the cost of the meal.
They left a tip of 15% of the cost of the meal plus tax.
What was the total cost of the meal, tax, and tip?

$42.06

Step-by-step explanation:

step 1: find the 6% of 34.50; by multiplying 34.50 x 0.06 ( 0.06 = 6/100 or 6%).

34.50 x 0.06 = 2.07

Step 2: 2.07 + 34.50 = 36.57 Total cost of meal + 6% tax.

Step 3: find 15% of 36.57

36.57 x 0.15 = 5.4855

Step 4: 36.57 + 5.49 (rounded because money only has two decimal places)

$42.06

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.
