Question

Sarah works $8$ hours a day for $22$ days in a month. How many hours does she work in a month?

• A. $162$ h
  
• B. $180$ h
• C. $176$ h
• D. $154$ h

Answer 1

The correct option is C $176$ h

Sarah works $8$ h a day for $22$ days.
To find the number of hours she works in a month, we need to multiply $8$ by $22$.

$8\times 22=?$

Let’s use the distributive property of multiplication to find the product.
The expanded form of $22:22=20+2$

$8\times 22=8\times (20+2)$

$=(8\times 20)+(8\times 2)$

$=160+16$

$=176$

Therefore, Sarah works $176$ h in a month.
