Atelevision normally sells for $320. this week, it's on sale at 60% off the normal price. what is the sale price? a) $101 b) $128 c) $256 d) $301

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.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
