When you have multiplying with same base, you add the power, for example here : z^6 * z^3 = z^(6+3) = z^9.
When you have dividing with the same base, you substract it, for example here : z^9/z^4 = z^(9-4) = z^5.
40.21/12.5
We would do this because the problem asks for unit rate
And and we need to find out the cost for one square foot
40.21/12.5 = 3.2168
We need to round this ANSWER and round it or else it will be incorrect
The answer would round to 3.22
Therefore, the answer is $3.22 per square foot
If you work out the equation the answer would be 5 but its not a definite answer.
