Question

I = prt is an example of _____.

a variable
an expression
a constant
a formula

Answer 1

Hint:

To calculate interest, I, you use the formula I = prt, where p is the principle, r is the interest rate, and t is time.

Answer 2

So, since you're calculating interest, is I = prt a variable, formula, expression, or a constant?

Answer 3

its a variable

Answer 4

No, it's not.

Answer 5

i, p, r and t are all variables.
i=prt enables you to find the interest when the principal, interest rate and time are given.
Try again: Is i-prt a variable, an expression, a constant or a formula?
