Laura goes shopping. she spends one-fourth of her money on a pair of shorts, and one-third of her remaining money on a belt. if laura has $42 left after these two purchases,, how much money did she have left when she started shopping

answer:

30

we formulate the equation 3/5x=18, as she spend 2/5, and so 18 is the 3/5 she has left. now with 3/5x=18, we multiply each side by 5/3, leaving x=18*5/3, and that gives us 30

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.
