A = 2.5x , where x = 7 since there is 7 days in a week. So it would be 2.5(7)
B = 2.5(30) where 30 represents how many days. So he eats 75 cookies in 30 days.

Answer:
0.0048cm/s
Step-by-step explanation:
Volume of the spherical balloon is expressed as;

dV/dt = dV/dr * dr/dt
Given
dV/dt = 5cm³/s
dV/dr = 4πr²
Since V = 972picm³
972π = 4/3πr³
972 = 4/3r³
4r³ = 972 * 3
r³ = (972 *3)/4
r³ = 729
r = ∛729
r = 9cm
dV/dr = 4π(9)²
dV/dr = 324π
dV/dt = dV/dr * dr/dt
5 = 324πdr/dt
dr/dt = 5/324π
dr/dt = 5/324(3.14)
dr/dt = 5/1017.36
dr/dt = 0.0048cm/s
