Answer:
12.94%
Step-by-step explanation:
r = 100(1/2)^(d/5) = 100((1/2)^(1/5))^d ≈ 100(.87055)^d
The daily decrease is 1 - 0.87055 = 0.12944 ≈ 12.94%
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
Hey there! :D
Find the unit rate.
275/2= 137.5
Cade shoots 137.5 free throws per hour. Multiply that by 5 for 5 hours.
5*137.5= 687.5
He can shoot 687.5 free throws in one hour. You could just round that to 688.
I hope this helps!
