The mean

Mean is calculated as:

$\bar x = \frac{\sum fx}{\sum f}$

So, we have:

$\bar x = \frac{5 * 4 + 10 * 6 + 14 * 7}{29}$

$\bar x = \frac{178}{29}$

$\bar x = 6.14$

Mathematics

(N stands for the number)So we do a simple problem:
$150,000 - N% = $67,500
$150,000 - 45% = $67,500
$67,500 is 45% of $150,000
Down payment
$150,000 - N% = $22,500
$150,000 - 15% = 22,500
$22,500 is 15% of $150,000
