for the 1st 2 minutes cost = 0.5*2 = 1
for the remaining minutes 10-2= 8*0.15= 1.2
total cost = 1 +1.2 = 2.2

$0.50 + 8($0.15) = $0.50 + $1.20 = $1.70.

The call costs $1.70

"cost $0.50 for the first 2 minutes" seems ambiguous to me...
I was confused whether each minute costs .5 or both cost .5...

0.5 for the first two minutes TOTALLY

Thinking about part/minutes/seconds in two minutes is pointless

2 minutes = 0.5. Straight
