Estimated bill amount is $57

Step-by-step explanation:

  • Step 1:

Round off the cost of 1 appetizer.

Cost of 1 appetizer = $6.50 ≈ $7

  • Step 2:

Find the cost of 2 main courses.

Cost of 1 main course = $15.75 ≈ $16

∴ Cost of 2 main courses = 2 × 16 = $32

  • Step 3:

Find cost of 2 drinks.

Cost of 1 drink = $2.25 ≈ $2

∴ Cost of 2 drinks = 2 × 2 = $4

  • Step 4:

Find the cost of 2 desserts.

Cost of 1 dessert = $7.25 ≈ $7

∴ Cost of 2 desserts = 7 × 2 = $14

  • Step 5:

Add all and find the total cost.

Estimated Total bill amount = 7 + 32 + 4 + 14 = $57

1) v=1 (Add 10 to both sides of the equation. You should get -9+10, which makes the answer 1)

2) v=7 (like number 1, add 10 to both sides of the equation. 10+-3=7)

3) x=7 (add 3 to both sides of the equation. 4+3=7)

4) m=29 (divide -377 by -13, you should get 29)

5) b=6 (add 7 to both sides of the equation. 7+-1=6)

6) p=5 (add 13 to both sides of the equation. 13+-8=5)

7) p=8 (divide 40 by 5)

8) a=-19 (Divide 418 by -22. The answer is -19.)

A total of 754 tickets were sold for the school play. They were either adult tickets or student tickets. There were 54 more stud
inn [45]
Answer: 350

Explanation:

a = adult tickets
s = student tickets

║ a + s = 754
║s = a + 54

Plug s = a + 54 into a + s = 754

a + (a + 54) = 754

a + a + 54 = 754

2a + 54 = 754

2a = 754 - 54 

2a = 700

a = 350
