Aphone company offers two monthly plans. plan a costs $30 plus an additional $0.15 for each minute of calls. plan b costs $16 plus an additional $0.20 for each minute of calls.
for what amount of calling do the two plans cost the same?
what is the cost when the two plans cost the same?

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

 x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

 280 minutes and cost $72 each
