Answer 2

A monthly bill is always like this: \(15 + m \times 0.04.\)

Can you write the inequality to solve (first, without solving it)?

Answer 3

15 + 0.04m < 57.68 ?

Answer 4

@reemii

Answer 5

It is the other way around: 15+0.05*m represents the amount to pay, while 57.68 is the Minimum she had to pay.
-> 15+0.05*m was always greater or equal to the smallest bill she ever had: 57.68
-> 15+0.05*m ≥ 57.68

Answer 6

ok so i solve the equation 15 + 0.05 x m > 57.68

Answer 7

853.6?

Answer 8

Yes. Now since you must give an whole number of minutes, you must round to the upper value: 854. (if m ≥ 853.6 and is integer, it is ≥ 854).

Answer 9

oh ok thanks for all your help :)

Answer 10
