A 16 B 18 C 17 D 21
13260 * 0.2 + $2,652 deposit
0.25 * 624 = $156 saved each week
Take it from there.
13260 * 0.2 = $2,652 deposit
To find out how many weeks you need to save in order to raise the deposit, we need to calculate the amount you save each week and then divide the deposit by that amount.
First, let's calculate how much you save each week. We know that you save 25% of your salary, which is $624. To find out how much you save, we can multiply $624 by 25% (or 0.25):
$624 * 0.25 = $156
So, you save $156 each week.
Next, let's calculate the deposit amount. We know that the car costs $13,260 and you need 20% of that for the deposit. To find the deposit amount, we can multiply $13,260 by 20% (or 0.20):
$13,260 * 0.20 = $2,652
So, the deposit amount is $2,652.
Now, let's calculate how many weeks you need to save in order to raise the deposit. To do that, we divide the deposit amount by the amount you save each week:
$2,652 / $156 = 17
Therefore, you need to save for 17 weeks to raise the deposit.
The correct answer is C - 17 weeks.
