Answer:
B) $128.
Step-by-step explanation:
For finding the answer, first we need to know about percentages.
1. Percentage of a number "x" can be found by multiplying "x" with the percentage (divided by 100),
x * Percentage/100
2. To find 60% of $320, we can use the above formula,
320 x 60/100 = 192
3. Since it is 60% off, we should subtract the original price with the 60% off value,
320 - 192 = 128
4. So the sale price is $128.
