Answer:
$132
Step-by-step explanation:
40% off means it is actually 60% of the regular price.
Thus, you will multiply the original (220) by .6 (this means 60 percent)
and you will get 220*.6=132
First, let's work with the denominator alone:
4⁻⁴ = 1 / 4⁴ = 1/256 .
The original problem is the reciprocal of that = 256.
