Answer:
Yes, 102 isn't a square number (1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144) so the square root of 102 will keept going forever and is irrational.
Step-by-step explanation:
basically
Let's call the store value as s and the wholesale price as w. A store prices tapes by raising the wholesale price 50%(0.5 in decimals) and adding 25 cents, writing this as an equation, we have
![s(w)=w+0.5w+0.25](https://tex.z-dn.net/?f=s%28w%29%3Dw%2B0.5w%2B0.25)
If we invert the equation we're going to find the the wholesale price as a function of the store price.
![\begin{gathered} s=w+0.5w+0.25 \\ s=1.5w+0.25 \\ s-0.25=1.5w \\ w(s)=\frac{s-0.25}{1.5} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20s%3Dw%2B0.5w%2B0.25%20%5C%5C%20s%3D1.5w%2B0.25%20%5C%5C%20s-0.25%3D1.5w%20%5C%5C%20w%28s%29%3D%5Cfrac%7Bs-0.25%7D%7B1.5%7D%20%5Cend%7Bgathered%7D)
Now, to find the wholesale price if the sales price is $1.99, we just need to evaluate s = 1.99 on the function we created.
![w(1.99)=\frac{1.99-0.25}{1.5}=1.16](https://tex.z-dn.net/?f=w%281.99%29%3D%5Cfrac%7B1.99-0.25%7D%7B1.5%7D%3D1.16)
The wholesale price is $1.16.
