He prepares to have lunch in a restaurant where he usually leaves as tip (tip) 15% of the total to be paid, that is, the consumption plus tax (tax). the tax in that county is 7% of consumption. he realizes he didn't bring his cards and only has $ 23 in cash. calculate the maximum value of the dishes you will order at lunch considering tax and tip. you must explain it step by step.

step-by-step explanation:

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
