Answer:
$1148 will be saved.
Step-by-step explanation:
Linear equation form: y=ax+b
Slope of the equation: (y2-y1)/(x2-x1), (150.50-80.50)/(7-3)= 70/4 = 35/2
So y=35/2x+b
Substitute x and why with (7, 150.50)
7=35/2 *150.5+b
b=28
The equation is 35/2x+28
There is 4 weeks in 16 months.
4*16= 64, 64 weeks.
Substitute 64 into x.
y=35/2 *64+28
y=1148
Hense, after 16 months, $1148 will be saved.
