Answer:

$21,250

Step-by-step explanation:

4% = 850

100% = x

Cross multiply the above to get 21,250

Another way of doing this is:

850 divided by 4 = 212.5

So every percent is equal to 212.5, so:

212.5 * 100 (for 100%) = 21,250

Find two integers whose product is -32 and whoes quotion is -2
Mandarinka [93]
-8 and 4. The product, -8 x 4, would be -32 (just think 8 x 4 = 32, then add the negative sign). The quotient, -8 / 4, would be -2 (just think 8/4 would be 2, then add the negative sign).

Travka [436]
We start with
$1,187.92
With the interest and the late fee charge
$1,187.92 (1 + 0.1225/12) + 30 = $1,230.05
With the interest minus the payment of $125
$1,230.05 (1 + 0.1225/12) - $125 = $1,117.60

The new principal after the latest payment is $1,117.60.
