Answer 1

It represents that , the amount of money in the bank account is $1680 after 50 months.

Explanation:

Given , the amount of money in a bank account can be represented by the equation A(m) = 30m +180, where A(m) is measured in dollar and m is measured in month.

When A(m) = 1680

1680 = 30m +180

⇔30m = 1680 -180

⇔30m = 1500

⇔
`m= (1500)/(30)`

⇔ m = 50

It represents that , the amount of money in the bank account is $1680 after 50 months.
