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.

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

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
