we are given
![p=900-4t^2](https://tex.z-dn.net/?f=p%3D900-4t%5E2)
where
price p( in dollars) of a new smartphone
t is the number of months since January
now, we can solve for t
step-1:
Add both sides by 4t^2
![p+4t^2=900-4t^2+4t^2](https://tex.z-dn.net/?f=p%2B4t%5E2%3D900-4t%5E2%2B4t%5E2)
![p+4t^2=900](https://tex.z-dn.net/?f=p%2B4t%5E2%3D900)
step-2:
Subtract both sides by p
![p+4t^2-p=900-p](https://tex.z-dn.net/?f=p%2B4t%5E2-p%3D900-p)
![4t^2=900-p](https://tex.z-dn.net/?f=4t%5E2%3D900-p)
step-3:
divide both sides by 4
![\frac{4t^2}{4} =\frac{900-p}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4t%5E2%7D%7B4%7D%20%3D%5Cfrac%7B900-p%7D%7B4%7D)
![t^2=\frac{900-p}{4}](https://tex.z-dn.net/?f=t%5E2%3D%5Cfrac%7B900-p%7D%7B4%7D)
![t^2=225-0.25p](https://tex.z-dn.net/?f=t%5E2%3D225-0.25p)
step-4:
Take sqrt both sides
![\sqrt{t^2} =\sqrt{225-0.25p}](https://tex.z-dn.net/?f=%5Csqrt%7Bt%5E2%7D%20%3D%5Csqrt%7B225-0.25p%7D)
![t=\sqrt{225-0.25p}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B225-0.25p%7D)
so, we get

Ok "smarty pants" I just tell the answer I also show the work and there is no work for me to do sorry but follow me and I'll help you out
Answer: 1.71, square root of pi, 16/9 and 13/4
Step-by-step explanation: first you need to make all of them into decimals in order to arrange them so, 13/4 = 3.25, square root of pi= 1.772, 1.71 = 1.71( already a decimal) and 16.9 = 1.777.
Once you have written them all in decimals you can now arrange them from least to greatest.
Answer:
