The expression for the total amount Bo paid is 1.308x, where x is the subtotal. It accounts for a 9% tax and a 20% tip on the entire bill, including tax.
The expression representing the total amount Bo paid can be calculated by adding the original subtotal (x) to the tax (0.09x) and the tip (0.20 × (x + 0.09x):
Total amount = x + 0.09x + 0.20 × (x + 0.09x)
Simplifying this expression gives:
Total amount = x + 0.09x + 0.20x + 0.018x
Combining like terms:
Total amount = 1.308x
The complete question is:
Bo goes to a restaurant and the subtotal on the bill was x dollars. A tax of 9% is applied to the bill. Bo decides to leave a tip of 20% on the entire bill (including the tax). Write an expression in terms of x that represents the total amount that Bo paid.
