Based on the charges to Anne's phone plan and that of AJ, the number of minutes of usage till Anne and AJ's plan cost the same is 1,000 minutes.

How long till Anne and AJ are charged the same?

Assuming that the number of minutes till Anne and AJ are charged the same is x, then Anne's phone plan can be represented as:

= 25 + 0.02x

AJ plan is:

= 5 + 0.04x

The number of minutes till both are the same is:

25 + 0.02x = 5 + 0.04x

25 - 5 = 0.04x - 0.02x

20 = 0.02x

x = 1,000 minutes
