BA&D's plan is better for those who use less data. The intersection point of the two plans is (2, 18), which means that both plans cost $18 when you use 2G of data. Anything using more data than that is less expensive with BA&D's plan.
To find the intersection point,
6+6g=10+4g
We cannot have a variable on both sides, so we will subtract 4g from both sides:
6+6g-4g=10+4g-4g
6+2g=10
Subtract 6 from both sides:
6+2g-6=10-6
2g=4
Divide both sides by 2:
2g/2 = 4/2
g = 2
This is the point where the plans cost the same. If we try a number smaller than 2 in both plans,
6+6(1) = 6+6 = 12
10+4(1) = 10+4 = 14
BA&D's plan is less.
