The mass of Beatrice was 127 kg after joining a slim fit programme the mass decreased at the rate of 3 kg per month find the lowest number of complete months that Beatrice has to be on the programme before his mess becomes less than 100 kg write down an inequality and then solve the problem

Answer 1

Let x represent the number of complete months Beatrice is on the programme.

The inequality representing the situation is:
127 - 3x < 100

Solving for x:
-3x < 100 - 127
-3x < -27
x > 9

Since x represents the number of complete months, Beatrice has to be on the programme for at least 10 months before her mass becomes less than 100 kg.
