Question

simple interest is computed by finding the product of the principal amount, p, and the interest rate, r, and the time t.translate each sentence into an formula

Answer 1

You have that simple interest is computed by the multiplication of p (principal amount), r (interest rate) and t (time).

The previoues sentence can be written algebraically as follow:

I = p x r x t you only have to multiply each factor

where I is the letter for simple interest.
