hello
1 500 - 785 = 715 minutes
715 minutes = 11 h et 55 minutes
1 500 - 785 = 715 minutes
715 minutes = 11 h et 55 minutes
x + 785 < = 1500......where x is the total number of minutes that can be used
x < = 1500 - 785
x < = 715 <== so she can use , at most, 715 more minutes
x < = 1500 - 785
x < = 715 <== so she can use , at most, 715 more minutes
