A 2-column table with 5 rows. Column 1 is labeled Item with entries Italian Salad, Fettucine Alfredo, Subtotal, Sales Tax (5 percent), Total. Column 2 is labeled Price with entries 3 dollars and 99 cents, 7 dollars and 17 cents, 11 dollars and 16 cents, 56 cents, 11 dollars and 72 cents. Abelita and Franco had great service during the meal. They would like to tip the server 20 percent. Which of these expressions would find the total bill, including tax and gratuity? Check all that apply. (0.2)(11.72) 11.72 – [(0.2)(11.72)] 11.72 + [(0.2)(11.72)] (1.2)(11.72) ASAP

(C)11.72+[(0.2)(11.72)]

(D)(1.2)(11.72)

Step-by-step explanation:

From the table:

The Total =$11.72

They would like to tip the server 20 percent. Therefore, their total bill will be :

We can also re-write this by factorizing as shown below:

The correct options are C and D,

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
