$6(.80) * 20x =12x* 11(.80)
4.80* 20x = 12x*8.80
-12x -12x
$4.80 * 8x = 8.80
-4.80 -4.80
8x=4
/8 /8
x=$.50
Proof;
6(.80) + 20(.50) = $14.80
12(.50) + 11(.80) = $14.80

Answer:
12.375 miles
Step-by-step explanation:
The distance between Ian's house and the park is 16 1/2 miles or 16.5 miles. His grandmother lives 3/4 of the way between Ian's house and the park. We need to know what is the 3/4 of such distance. Lets say Ian's house is at mile 0 and the park is at mile 16.5 in a distance line.
We can find the position of his grandma's house by multiplying such distance by 3/4 or 0.75, which is equivalent:
grandma = 16.5 * 0.75 = 12.375
So, on our distance line her grandma is at the position mile 12.375.
As Ian is at the mile 0 and his grandma's house is at 12.375 miles away from Ian's house.
