Question

The Shake Shack sells large and small shakes. A large shake costs $5, and a small shake costs $3. On Sunday, the Shake Shack had a total revenue of $479. Which equation can be used to represent x, the number of small shakes sold and y, the number of large shakes sold?
479x + 479y = 15

4x + 4y = 479

5x + 3y = 479

3x + 5y = 479

Answer 1

Hey there !

Thanks for the question !

Here's the answer !

Large Shake = $ 5

Small Shake = $ 3

Total Revenue made on that day = $ 479

So, Let 'x' be the total number of large shakes bought on that day and 'y' be the total number of small shakes bought on that day.

So 5 × x = Total Revenue made in Large Shake

=> 5x = Total Revenue made in large shake.

Also, 3 × y = Total Revenue made in Small shake

=> 3y = Total Revenue made in small shake.

Total Revenue = Revenue made in Large shake + Revenue made in small shake

=> $ 479 = 5x + 3y

=> 5x + 3y = 479

Hence this is the required equation.

Option (C) is the correct answer.

Hope my answer helped !
