Darnell pays $12 for unlimited texting and calling on his phone each month. An alternative phone plan would charge $1 per 30 texts and $3 per 20 minutes of calls per month. Darnell sends 60 texts and spends 60 minutes on the phone each month. How many dollars less would he pay on the alternative plan?

How many texts does Darnell send? ** Darnell would pay 60 / 30 = <<60/30=2>>2 times the $1 texting charge per month.
How many minutes does Darnell spend on the phone? ** He would pay 60 / 20 = <<60/20=3>>3 times the $3 call charge per month.
How many dollars less would Darnell pay on the alternative plan? ** He would pay 2 * 1 + 3 * 3 = 2 + 9 = $<<2*1+3*3=11>>11 per month on the alternative plan.
How many dollars less would Darnell pay on the alternative plan? ** Thus, Darnell would pay 12 - 11 = $<<12-11=1>>1 less on the alternative plan.
