Answer to Problem 34PPE

  $x-2$

Explanation of Solution

Given information:

Serena and Tyler were wrapping gift boxes at the same pace. Serena starts first. Serena wrapped $x$ boxes.

  

Calculation:

Here, we have to find the algebraic expression that represents the number of boxes rapped by Tyler:

As, it is given that Serena wrapped $x$ boxes.

Now,

In the first figure she wrapped only $2$ gift boxes.

In the second figure she wrapped $3$ gift boxes and he wrapped $1$ gift box.

In the third figure she wrapped $4$ gift boxes and he wrapped $2$ gift box.

Thus, the expression will be:

  $numberofboxesthathehaswrapped=numberofboxesshewrappped-2$

Hence, the expression will be $x-2$ .
