Answer 1

Heyo kiddo. How ya doin today?

Part A:
20x = 300
/20 /20
x = 15

Hue needs to run 15 miles to ear $300 for the charity.
_____________________________________________
Part B:
10x = 300
/10 /10
x = 30

Hue needs to be paid $30 per mile to achieve her goal.


You're welcome. :)

Answer 2

A)

let m = miles

300=20m

divide each side by 20 to find m

300/20 = 15 miles


B)

let d = dollar amount per mile
like the first one just use 10 instead of 20

300 = 10d

divide both sides by 10 to find d

300/10 = 30 dollars per mile
