Respuesta :

She makes 4 birdhouses in 3. hours. If you double that you get 8 birdhouses in 7 hours. The answer is C. Please put me as brainliest.

Option C: 7 hours to build 8 house,

Whenever getting work-time related questions, it is needed to focus that as the amount of work done increases, the time needed to complete also increases.

Given that:

3.5 hours of work is needed to build 4 birdhouses.

Thus as we increase the time twice, the number of birdhouses build by the same person Jasmine will be twice as she got double time, thus building 2 times 4 i.e. 8 birdhouses.

Thus we have:

Jasmine takes 7 hours of work to build 8 birdhouses.

Therefore we see that Option C: 7 hours to build 8 birdhouses is correct.
