Given Jenny has saved over the last 12 months.
She saved either or
a month.
Let the number of months to save be x
Let the number of months to save be y
Total period is 12 month.
Jenny has saved $3,800 over the last 12 months.
Dividing both side from 50 we get,
Now Multiplying equation 1 by 5 we get,
Now Subtracting Equation 3 by equation 2 we get,
Substituting the value of y in equation 1 we get,
∴ Jenny save 4 Months of and 8 Months of
in a 12 month duration
Reference the image below if you need to.
We start at red point (0,0) and reflect across blue line x= -3.
This puts the point equidistance away on the opposite side at blue point (-6, 0).
That point is then reflected across green line y= -3,
and ends up at green point (-6, -6).
