PLEASE ANSWER!!!

In 1987, 34.7 million households owned a dog, and 27.7 million
owned a cat. Since then, dog ownership has decreased by 0.025
million households per year, and cat ownership has increased by
0.375 million households
per year. How many years, y, will it
take for them to be equal?

Respuesta :

Answer:

y=17.5

Step-by-step explanation:

y=# of years

34.7-0.025, you subtract since it has decreased.

27.7+0.375, you add since it increased.

Put them into equations:

34.7-0.025y=27.7+0.375y

*whatever you do to one side, you do to the other*

Solve the equation and get y=17.5
