Question

John's goal is to have more than -7 dollars in his bank account by the end of the month. The variable d is the number of dollars in John's bank account at the end of the month. Write an inequality in terms of d that is true only if John meets his monthly goal.

Answer 1

d > -7. Notice that it is > and not >=, because it is more than. Curious it says -7 dollars, and not a positive value

Answer 2

d > - 7

Explanation:

Here, d represents the number of dollars in John's bank account at the end of the month.

As per statement,

In John's account,

The balance must be more than -7 dollars,

That is, Number of dollars at the end of each month > - 7 ( '>' is used for more than )

⇒ d > - 7

Which is the required inequality.
