Final answer:
Miranda saved approximately 37.22% of the total amount needed to buy the computer in the first month.
Step-by-step explanation:
To find out what percent Miranda saved in the first month, we need to first determine how much money she saved in the first month. Miranda worked 33.5 hours in the first month, so we can calculate her income by multiplying the number of hours worked by her hourly wage. Let's assume her hourly wage is $10. Therefore, her income for the first month is 33.5 hours * $10/hour = $335.
To find the percentage of this amount relative to the total amount needed to buy the computer, we need to divide the amount saved in the first month by the total cost of the computer and then multiply by 100. The amount saved in the first month is $335, and the total cost of the computer is $900. So, the percentage saved in the first month is ($335/$900) * 100% = 37.22%.
Therefore, Miranda saved approximately 37.22% of the total amount needed to buy the computer in the first month.
