Expression B
Step-by-step explanation:
<em>Let us find the information in the question</em>
- Alejandro has gon to school
of the last 35 days - We need to find the expression that represents the number of days Alejandro has gone to school.
<em>We must write the given information in an expression then look for it in the choices.</em>
∵ He has gone
of 35 days
→ "of" means times (×)
∴ The days that he has gon = 35 × 
<em>The expression that can be used to determine the number of days he has gone to school is</em> 35 ×
