B) $57
C) $61
D) $69

Answer 1

Estimated bill amount is $57

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
