Talja [164]

Answer: <u>30</u>

Step-by-step explanation:

Yvette- <em>100-7</em>

Isandro- <em>0+3</em>

1.) I'm going to speed up the process and multiply by 5.

Yvette: <em>100-7</em>

7  × 5 = 35

100-35= 65

65-35= 30

Isandro: <em>0+3 </em>

3 × 5 = 15

0+15= 15

15+15=<em> </em>30

2.) If they keep going on this pattern they will have the same number on the 10 round.
