Jordan wants to use an 18% employee discount for the new I-phone. There is a 8.5% tax applied after the discount. If the I-phone costs $349.99, what is the total cost Jordan will pay for the I-phone after tax? Write the correct response and explain how you arrived at your answer on the lines below. *

$311.49

Step-by-step explanation:

*remember when turning percents to decimals you move the decimal to spots to the left. so 5% as a decimal is 0.05 and 10% as a decimal is 10

step 1) multiply 349.99 by 0.18 to find the price of discount. 349.99 times 0.18 is 62.9

step 2) subtract 62.9 from 349.99 to find the price with the discount. the answer is 287.09

step 3) multiply 287.09 times 0.085 to find the price of the tax. which is 24.4

step 4) add 287.09 and 24.4 which is 311.49

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
