How much total money does someone have if they receive $20 a week for 4 weeks?

• A. $60
• B. $80
• C. $100
• D. $120

Answer: (B)

To determine the total amount of money received over the given time period, you need to multiply the weekly amount by the number of weeks. In this case, the person receives $20 each week and does so for 4 weeks.

Calculating this involves simply multiplying the two numbers:

[

20 \text{ (dollars per week)} \times 4 \text{ (weeks)} = 80 \text{ dollars}

]

Therefore, the total amount of money the person has after 4 weeks is $80. This calculation shows how understanding basic multiplication can easily help solve problems involving repeated addition, such as earning a consistent amount of money over time. This is why the correct answer is $80.
