Final Answer:
If a student saves $35 per week, he takes 30 weeks to save enough money to buy a computer. So the correct answer is C) 30 weeks.
Step-by-step explanation:
To determine the number of weeks needed to save enough money to buy a computer at a rate of $35 per week, we divide the total cost of the computer by the weekly savings. If the computer costs x dollars, the equation to find the number of weeks is x / $35.
Let's assume the computer costs $1,050. To calculate the number of weeks required:
$1,050 / $35 = 30 weeks
Therefore, it would take 30 weeks for the student to save enough money to buy the computer. This result aligns with option C) 30 weeks provided in the question.
The formula used here is simple division: dividing the total cost of the computer by the amount saved each week gives the number of weeks needed to reach the goal. In this case, dividing the computer's cost by the student's weekly savings of $35 reveals that it would take 30 weeks to accumulate enough funds to purchase the computer. This method can be applied universally to calculate the time required to save for any goal when a consistent saving amount is known.
