Answer:
c
Step-by-step explanation:
Reflection across the x-axis reverses the sign of the y-values
Since a ratio can also be written to look like a fraction, you can use your knowledge of creating equivalent fractions to this to create equivalent ratios. i.e: 5:10 can be written as 5/10, you can simplify it to 1/2 (1:2) or multiply it by 2/2 to get 10/20 (10:20).
For this case we must raise an inequality.
We have "d" dollars initially and they are spent 12. Then:

At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expression
, that is:

Resolving:

There are at least 63 dollars left in the account.
