Atennis racket normally costs $80. the tennis racket is on sale for 40% off. what is the sale price of the tennis racket?

80 * .4 = 32

32 dollars off

80 - 32 = 48

The sale price is 48

$48.00

Step-by-step explanation:

There is another way of thinking about it. If there is a 40% reduction in price, it means that he is paying 60% of the full price

Sale price = 60% of 80 dollars. Of means multiply in % language.

Sale price = (60/100) * 80 = 60 * 80/100 = 4800/100 = 48 Dollars. The price he ought  to pay is 48 dollars.

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.

no one knows lol
