After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8 percent.

lisov135 [29]

Answer:

Tip = $10.52

Tax = $4.21

Total bill = $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax bill = $52.60

Tip to waiter = 20% of the pre-tax amount

Tip to waiter =

$20\%\times \text{Pre-tax amount}\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52$

Thus, $10.52 was given to waiter.

Tax on bill = 8% of the pre-tax amount

Tax =

$8\%\times \text{Pre-tax amount}\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21$

Thus, tax on bill was $4.21.

Total bill =

Pre-tax amount + Tax + Tip

$=52.60 + 4.21 + 10.52\\=67.33\$$

Thus, the total bill is $67.33

At the city museum, child admission is $5.90 and adult admission is $9.70. On Tuesday, three times as many adult tickets as chil

valina [46]

Answer:

$\large \boxed{31}$

Step-by-step explanation:

1. Set up the equations

Let a = the number of adult tickets

and c = the number of child tickets. Then

9.70a = revenue from adult tickets and

5.90c = revenue from child tickets

9.70 a + 5.90c = total ticket revenue

You have a system of two equations:

$\begin{cases}(1) & a = 3c\\(2) & 9.70a + 5.90c = 1085\end{cases}$

2. Solve the equations

$\begin{array}{lrcll}(3) & 9.70(3c) + 5.90c & = & 1085 &\text{Substituted (1) into (2)}\\& 29.10c + 5.90c & = & 1085 &\text{Simplified}\\& 35c & = & 1085 &\text{Simplified}\\& c & = & \dfrac{1085}{35} &\text{Divided each side by 35}\\\\(4) && = & \mathbf{31} &\text{Simplified}\\\end{array}\\\text{The museum sold $\large \boxed{\textbf{31 child tickets}}$}$
