b.
$1,370.52

c.
$2,043.60

d.
$2,741.04

$2970.25

Step-by-step explanation:

Please write the formula all on one line:

M = P(1 + r)^n, where P is the principal, r is the annual interest rate as a decimal fraction and n is the number of years.

Here, that comes to:

M = $2,500(1 + 0.09)^2, or

    = $2,500 (1.09)^2, or

M   = $2,500(1.1881), or

M = $2970.25.

$2970.25 will be needed to pay back this $2,500 loan.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
