The federal government spends $25.2 million each year to operate parks and historic sites in Washington D.C. This is $7.8 million more than it spends to run Yellowstone National Park. How much does it cost to run Yellowstone National Park? Write an equation to model the following situation. Use y as your variable for Yellowstone.

Respuesta :

Answer:

y + 7.8 = 25.2

y = 17.4

Step-by-step explanation:

y + 7.8 = 25.2

(now we solve the equation .... we substract 7.8 from each side of the equation )

y = 25.2 - 7.8

y = 17.4
