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:-)
(x² + 16)(x² - 16)
= (x²)² - 16²
= x⁴ - 256
your answer would be 9 fish are left in the tank
