Herbie has a mass of 100 kg
His personal trainer sets a goal for him
to lose 2 kg per month until he reaches
his goal mass. An equation for this
relation is m = 100 -
100 - 2n, where n
represents the number of months and
m represents Herbie's mass in
kilograms.
a) Use the equation to create a table
of values.
b) At some time, Herbie should have a
mass of 60 kg. How many months
will he have trained?
c) By his birthday, Herbie had trained
for 7 months.
