Answer 2

let x = number of minutes spent making international calls

Answer 3

if it costs $0.10 per minute to make international calls, then how much does it cost if you use up x minutes making international calls ?

Answer 4

Y=0.10x+25
y=0.10(150)+25
y=40
in other words the user has to pay 40 dallors for using 150 minutes of international calls.
