Margaret is treating her best friend to a birthday dinner. Before ordering, Margaret wants
to have an idea of the final bill. The order includes one appetizer for $6.50, two main
courses for $15.75 each, two drinks for $2.25 each, and two desserts for $7.25 each.
Round each amount up to the nearest whole dollar to find an overestimate of the total
cost.
A) $34
B) $57
C) $61
D) $69

Estimated bill amount is $57

Step-by-step explanation:

Round off the cost of 1 appetizer.

Cost of 1 appetizer = $6.50 ≈ $7

Find the cost of 2 main courses.

Cost of 1 main course = $15.75 ≈ $16

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

Find cost of 2 drinks.

Cost of 1 drink = $2.25 ≈ $2

∴ Cost of 2 drinks = 2 × 2 = $4

Find the cost of 2 desserts.

Cost of 1 dessert = $7.25 ≈ $7

∴ Cost of 2 desserts = 7 × 2 = $14

Add all and find the total cost.

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