The volume of a substance, A, measured in cubic centimeters increases according to the exponential growth
dA
model =0.3A, where t is measured in hours. The volume of another substance, B, also measured in cubic

dB
centimeters increases at a constant rate of 1 cm3 per hour according to the linear model =1. At t = 0,
dt
substance A has a volume A(0) = 3 and substance B has size B(0) = 5. At what time will both substances have
the same volume? (1 point)
