The Keller family spent a total of $63.04.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
First, let's find the cost of the meal before tax and tip.
We know that the total bill, including tax, is $55.35, which is equal to 100% + 8% (the tax rate) = 108% of the original meal cost.
We can set up an equation to solve for the original meal cost (let's call it x):
x + 0.08x = 55.35
Simplifying the left-hand side:
1.08x = 55.35
Dividing both sides by 1.08:
x = 51.25
So the cost of the meal before tax and tip was $51.25.
Next, let's calculate the amount of tax they paid:
0.08x = 0.08(51.25) = 4.10
So the tax they paid was $4.10.
Now let's calculate the tip they left for the server. They left a 15% tip on the original meal cost of $51.25:
0.15(51.25) = 7.69
So the tip they left was $7.69.
Finally, to find out how much they spent in total, we add up the cost of the meal, the tax, and the tip:
51.25 + 4.10 + 7.69 = 63.04
Therefore, the Keller family spent a total of $63.04.

Complete question:
The Keller family's dinner bill is $55.35. This includes an 8% meal tax and a 15% tip on original meal for the server how much did they spend in total?
Answer:
The to one decimal is 54.6
Step-by-step explanation:
we need to calculate to one decimal.
Since, ....(1)
To calculate , put x=4 in equation (1)
simplify the above expression
calculate with the scientific calulator
< 0.1 =54.6
Hence, to one decimal is 54.6
(2) (p^2 - 9)(p^2 - 9)
(3) (p^2 + 9)(p + 3)(p - 3)
(4) (p + 3)(p - 3)(p + 3)(p - 3)
The expression p^4 - 81, when factored completely, is equivalent to (p^2 + 9)(p^2 - 9) using the difference of squares formula.
When the expression p^4 - 81 is factored completely, it becomes equivalent to (p^2 + 9)(p^2 - 9). This can be calculated using the rule of difference of squares which states that a^2 - b^2 = (a - b)(a + b). Here, p^4 can be considered as a square of p^2 and 81 as a square of 9. Hence p^4 - 81 = (p^2)^2 - 9^2. Applying difference of squares formula we get (p^2 - 9)(p^2 + 9).
