Model B

Step-by-step explanation:

Model B correctly displays sienna’s and jacob’s equations.

For sienna, the \$8 can be represented as 8 unit blocks, which is displayed in model 2. The \$3 per week can be represented as 3 x tiles, as shown in the picture, because it represents how many weeks.

For jacob, the model shows 6 unit blocks which represents his 6 dollars. The \$4 per week is represented with the 4 x tiles, and we use x tiles because we are calculating how many weeks.

2. Let the amount saving by Sienna and Jacob be x

Sienna has \$8 and is saving \$3 per week

So the equation will be 3x + 8

Jacob has \$6 and is saving \$4 per week

So the equation will be 4x + 6

Sienna will have same amount as Jacob, so

3x + 8 = 4x + 6

So the model two will represents the equation that Sienna will have same amount as Jacob.
