The graph line gets Smaller
4^3 * 4^3 = m^6....when multiplying exponents with the same base, the exponents are added and the base number remains the same....so m = 4
4^3 * 4^3 = 4^6
If she wants to only use 85 a month then doing the math it would be 85-65=20 divided by 5 equals 4 so she would get 4 gigabytes while staying within her budget :)
Brainiest please
