Answer:
![c=\frac{99}{32}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B99%7D%7B32%7D)
Step-by-step explanation:
The given quadratic equation is
.
Comparing this equation to:
, we have a=2,b=-5.
Where:
and ![x_1x_2=\frac{c}{2}](https://tex.z-dn.net/?f=x_1x_2%3D%5Cfrac%7Bc%7D%7B2%7D)
The difference in roots is given by:
![x_2-x_1=\sqrt{(x_1+x_2)^2-4x_1x_2}](https://tex.z-dn.net/?f=x_2-x_1%3D%5Csqrt%7B%28x_1%2Bx_2%29%5E2-4x_1x_2%7D)
![\implies 0.25=\sqrt{(2.5)^2-4(\frac{c}{2})}](https://tex.z-dn.net/?f=%5Cimplies%200.25%3D%5Csqrt%7B%282.5%29%5E2-4%28%5Cfrac%7Bc%7D%7B2%7D%29%7D)
![\implies 0.25^2=6.25-2c](https://tex.z-dn.net/?f=%5Cimplies%200.25%5E2%3D6.25-2c)
![\implies 0.0625-6.25=-2c](https://tex.z-dn.net/?f=%5Cimplies%200.0625-6.25%3D-2c)
![\implies -6.1875=-2c](https://tex.z-dn.net/?f=%5Cimplies%20-6.1875%3D-2c)
Divide both sides by -2
![c=\frac{99}{32}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B99%7D%7B32%7D)
Answer:
Amount spent by Tony = $49
Amount spent by Molly = 2 * 14
[49] + [2*49 + 14 ] = $161 = amonut spent by both
2/5+3/4 is the answer to it
