In october, jean shopped around local car dealerships for the best price on her dream car. when jean finally located what she was looking for, the business manager informed her that she will need a 25% down payment. if the retail price of the car was $18,250, calculate jean's down payment. calculate the down payment using the percent model.
a. $456.25
b. $73,000
c. $13,437.50
d. $4562.50

Option d.

Step-by-step explanation:

The retail price of the car = $18,250

Jean will need to pay 25% down payment.

Jean's down payment for the car = 25% of 18,250

                                                       =

                                                      = 0.25 × 18,250

                                                      = $4562.50

The amount of down payment would be $4562.50

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.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
