Un empresario de actividades artísticas invierte una gran cantidad de dólares por la presentación de un conjunto musical. Una falla en la gestión del departamento de promoción provoca pérdidas por U$ 15.000 que corresponden a un 20% de lo invertido. a) ¿Cuántos dólares invirtió el empresario en este negocio? b) Cual sería la el IVA, de la cantidad invertida?

5 cm

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60

Answer: a. - n ( 0.7 + ( - 0.7 ) )
