Answer:

z = 0.143

Step-by-step explanation:

2³z+9 = 8²z+1

1. Subtract 1 from both sides

2³z+8 = 8²z

2. Solve exponents

8z+8 = 64z

3. Subtract 8z from 64z

8 = 64z-8z

8 = 56z

4. Divide 8 by 56 in order to isolate z

8/56 = z

0.143 ≈ z

The local shelter decided to build an addition for cats hey borrowed $6300 from a local bank at a rate of 8% the high school hel

Zepler [3.9K]

Answer:

$378

Step-by-step explanation:

To find the interest that the shelter payed on this loan, we use the formula: $I=Prt$ .

P = $6,300

r = 8% or 0.08

t = 9/12

Now we substitute the values into our formula.

$I=Prt$ .

$I=6,300(0.08*\dfrac{9}{12})$

$I=6,300(0.08*0.75)$

$I=6,300(0.06)$

$I=$378$

So the shelter payed a total of $378 in interest to the bank.
