Final answer:
Jessica will reach her goal of saving $1000 in 8 weeks by depositing $50 per week, considering she already has $600. Option A is correct answer.
Step-by-step explanation:
The question pertains to how long it will take for Jessica to save $1000 if she has $600 in her checking account and deposits $50 each week towards her goal.
To calculate this, we subtract the initial amount of $600 from the target amount of $1000, which is equal to $400. This is the amount Jessica needs to save. Since Jessica saves $50 per week, we then divide the remaining amount to be saved ($400) by her weekly deposit ($50 per week).
The calculation is as follows:
$400 รท $50 per week = 8 weeks.
Therefore, in addition to the $600 Jessica already has, it will take her 8 weeks to save a total of $1000, making option a) 8 weeks the correct answer.
