Sandy's monthly phone bill expense is equal to ten times her age now. In two years, Sandy will be three times as old as Kim. If Kim is currently 10 years old, calculate Sandy's monthly phone bill expense.
If Kim is currently 10 years old, she will be 10+2 =<<10+2=12>>12 years old in two years.
In two years, Sandy will be three times as old as Kim, meaning Sandy will be 3*12 = <<3*12=36>>36 years old.
Currently, Sandy is 36-2 = <<36-2=34>>34 years old.
If Sandy's monthly phone bill expense is equal to ten times her age now, she pays 10*34 =$<<10*34=340>>340 in phone bill expense
