Answer:
..
Step-by-step explanation:
X=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100
answer is 7 months
You need to look at the x values when you calculate that.
There is a line which goes from -2 to 0. Another line at 0 to 4 and the last line is 7 to infinity.
You can combine the first two and get B) (-2, 4] and [7, infinity)
