At a restaurant, you order an appetizer for $5.25, a meal for $12.75, and a drink for $2.99. If the sales tax is 9%, what is the
Yuliya22 [10]

Answer:

 $22.88

Step-by-step explanation:

The total bill is the subtotal plus tax. The tax is computed by multiplying the tax rate by the subtotal, which is the total of all items being billed.

  subtotal = $5.25 +12.75 +2.99 = 20.99

  tax = $20.99 × 0.09 = $1.89

The total bill is ...

  subtotal + tax = $20.99 +1.89 = $22.88

2(x + 2) + 2 = 2(x + 3) + 1
Maslowich

Answer:

No solution

Step-by-step explanation:

5(x + 4) – x = 4(x + 5) – 1

x = ?

Solution:

5(x+4)−x=4(x+5)−1

Apply Distributive property:

  • (5)(x)+(5)(4)−x=(4)(x)+(4)(5)−1
  • 5x+20−x=4x+20−1

Combine Like Terms:

  • (5x−x)+(20)=(4x)+(20−1)
  • 4x+20=4x+19
  • 4x+20=4x+19

Subtract 4x from both sides:

  • 4x+20−4x=4x+19−4x
  • 20=19

Subtract 20 from both sides:

  • 20−20=19−20
  • 0=−1

There isn't any solutions.

4. The cost of a new house is being reduced 22%
olganol [36]
1. Ok so first I would find 22% of 212,000 to do that you do: 22 divide 100 = 0.22

2. Now that you’ve turned 22% into a decimal as 0.22 you find what 22% of 212,000 is like so: 0.22x212,000 =46,640


3. Now that you have to reduce 212,000 but 22% to do this you just subtract: 212,000-46,640= 165,360

They would purchase the house for $165,360
