Pretty sure you'd use the decay formula y = b(1-r)
so y = 20,000(1-0.25)
which equals $6328
The t and the 4 are supposed to be superscripts
The answer would be 1$. 10-3 (to steve) =7
7-6 (to anderson) = 1
The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
7 1/4 - 5 3/4= 1 1/2 because you can either 1) change it into decimals: 7.25-5.75 and do simple subtraction or... 2) u can change the 7 to a 6 and add 4 to the numerator of 1/4 making the equation 6 5/4 - 5 3/4 = 1 2/4 which simplified to 1 1/2 I hope I didn’t confuse you! :))
