Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%
Hope it helps:-)
Answer:
-20 divided 5 is the right answer.
Your welcome!
Step-by-step explanation:
VW=VC+CW
61=z+13+z+8
61=2z+21
2z=40
z=20
5 x 4 = 20 + 5 = 25
5 x 4 = 20 (black cats), and if you add the number of white cats to that(5) you get 25. So zoe has 20 more black cats than she does white cats
