Question

In a cafeteria, q burgers were sold last week, while 3 less than twice of it were sold this week. If each burger costs 4 dollars, which one of the following expressions gives the cost of burgers sold this week?

• A. 4(2q - 3) dollars
• B. 4(2q + 3) dollars
• C. 3(2p - 4) dollars
• D. 3(4p - 2) dollars

Answer 1

The correct option is A 4(2q - 3) dollars

Cost of 1 burger = 4 dollars

Burgers sold last week = q

Number of number sold this week = 3 less than twice of the burgers sold last week.

Burgers sold this week = 2q - 3

Hence, the total cost of burgers sold this week is 4(2q - 3) dollars.
