We have been given that you went to Walmart and spend $75. Of the total bill, $45.50 included non-taxable items.
Let us find the amount of taxable items by subtracting amount of non-taxable items from total bill.
![\text{Amount of taxable items}=\$75-\$45.50](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20taxable%20items%7D%3D%5C%2475-%5C%2445.50)
![\text{Amount of taxable items}=\$29.50](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20taxable%20items%7D%3D%5C%2429.50)
We have been given that the rate of tax is 7.5% to the taxable items. To find the amount of tax, we will find 7.5% of $29.50.
![\text{Amount of tax}=\$25.50\times \frac{7.5}{100}](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20tax%7D%3D%5C%2425.50%5Ctimes%20%5Cfrac%7B7.5%7D%7B100%7D)
![\text{Amount of tax}=\$25.50\times 0.075](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20tax%7D%3D%5C%2425.50%5Ctimes%200.075)
Final amount of bill would be amount of bill plus amount of tax.
![\text{Final amount of bill}=\$75+\$2.2125](https://tex.z-dn.net/?f=%5Ctext%7BFinal%20amount%20of%20bill%7D%3D%5C%2475%2B%5C%242.2125)
![\text{Final amount of bill}=\$77.2125](https://tex.z-dn.net/?f=%5Ctext%7BFinal%20amount%20of%20bill%7D%3D%5C%2477.2125)
Therefore, final amount of bill would be

<span>Use the definition of continuity.
A function is continuous at a point x = a iff
lim [x → a] f(x) = f(a)
In other words, a function is continuous at a point if its value is equal to its limit at that point.
So, for f(x) to continuous at x = 4 we must have
lim f(x) = f(4)
x → 4
