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?

(Use decimal notation. Give your answer to one decimal place.)

1 answer

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.
