Question

The combined area of Jasper National Park and Banff National Park is about 17 500 km. The area of Banff NAtional park is 900 km greater than half the area of Jasper National Park. Find the area of Banff national Park.

Answer 1

Let x be equal to the area of Jasper, and y be equal to the area of Banff. We then have:
x+y=17500
y-x=900
We can rearrange equation 2 to be y=900+x
Substitute into equation 1 and we get x+900+x=17500
This becomes 2x=16600
So x=8300 km
Then y=8300+900=9200 km
So the area of Banff is 9200 km

Answer 2

But what about the "The area of Banff NAtional park is 900 km greater than HALF THE AREA of Jasper National Park" sorry for caps idk how to underline

Answer 3

Lol btw I was born in Markham :P nice to know your from Mississauga

Answer 4

Oh shoot, didn't see the half. Allow me to fix that:
x+y=17500
y-x/2=900
Proceed as in my initial reply, and you will eventually get:
Something to the effect of 1.5x=16600
So area of Banff is approximately 6433.3 km... This is closer to the actual value according to Wikipedia.

Answer 5
