Tres compañías aportan capitales para hacer una investigación la estrella aporta 509000 724 flechabús la mitad de lo que aporta
Step2247 [10]

Answer:

En total, se invirtieron $960,000 por parte de las tres empresas.

Step-by-step explanation:

Para resolver cuánto dinero aportaron en total las tres empresas, es necesario determinar la cantidad de dinero que cada una de ellas aportó en forma particular. Así:

La Estrella: 509,000

Flechabus: (509,000 / 2) + 23,184

                   254,500 + 23,184

                   277,684

La Terminal: ((509,000 / 2) + 23,184) - 104,208

                     277,684 - 104,208

                     173,476

Ahora bien, para determinar el total invertido se requiere sumar dichos montos: 509,000 + 277,684 + 173,476 = 960,160

Así, en total, se invirtieron $960,000 por parte de las tres empresas.
