To find the answer, we need to set up an equation where B = 660 and then solve for t.
660 = 300 x 1.3t
Divide both sides by 300:
2.2 = 1.3t
Divide both sides by 1.3:
t = 1.69
Therefore, it will take approximately 1.7 years for the value of the account to increase to $660.
The value of a certain account after 𝑡
years is given by 𝐵=300×1.3𝑡 dollars.
How long will it take for the value of the account to increase to $660?
