Question

Which equation can be used to find the number of minutes a customer used if you know a and c?

1) m = (c - 12) / a
2) m = (c + 12) / a
3) m = (c - 12) * a
4) m = (c + 12) * a

Answer 1

Without additional context, it's impossible to determine which equation correctly represents the relationship between the number of minutes a customer used and the variables 'a' and 'c'. More information about how these variables are defined in the scenario is necessary to provide a precise answer.

Step-by-step explanation:

To find the number of minutes a customer used if you know the variables a and c, you need to choose the correct equation from the provided options. Based on the information given, it is not possible to decisively choose one correct equation without additional context or understanding of what the variables represent. In general, linear equations like these take the form of y = mx + b, where m represents the slope or rate, and b represents the y-intercept. Without knowing how a and c relate to the number of minutes (m), none of the equations can be confirmed as correct. More information is needed to solve this question accurately.
