Question

Can you write a real world problem for 2(3x+1)=14?

Answer 1

John and Paul want to go to the cinema, they know that the ticket costs $1 and each food box cost $3. If they spent $14, how many food boxes did each of them buy?

In this case since there is two people, we include that 2. 3x is representing the cost for buying x food boxes and 1 the cost for the ticket. 14 is the total amount of money spent.

`\begin{gathered} 2(3x+1)=!4 \\ 3x+1=7 \\ 3x=6 \\ x=2 \end{gathered}`

Each of them buy 2 food boxes.
