3! =3 x 2 x 1 = 6
Y!= Y x (y-1) x ... x 1=
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
So she earns $60 per day working, but only saves $50. To solve this equation you have to multiply $50 to each day she works. If the total has to be exactly $2,000 then you must multiply 50 x 36.4 and that equals $2,000.
Your answer should be 36.4 days.
If you would like to know the solution to the system of equations, you can do this using the following steps:
y = –5x + 3
<span>y = 1
</span>_______________
1 =<span> –5x + 3</span>
5x = 3 - 1
5x = 2 /5
x = 2/5 = 0.4
(x, y) = (0.4, 1)
The correct result would be (0.4, 1<span>).</span>
