Answers
For every original price, there is exactly one sale price.
Step-by-step explanation:
We are given the chart below lists the original and sale prices of items at a clothing store;
Original price Sale price
$7.99 $15.99
$5.59 $11.19
$10.99 $24.99
$7.69 $17.49
$12.99 $29.99
$9.09 $20.99
The statement that best describes that the sale price is a function of the original price is that For every original price, there is exactly one sale price because for any given function there is always an input value and an output value.
In this case, our input value is the original price of the clothes and the output value is the sale price of clothes. Now, if we have two sale prices for a single original price amount, then it will be confusing for the customers to consider which is the exact or true sale price.
So, this proves that in these scenarios, it is better to have only one output value for every input value. Also, we can observe in the data above that for every original price amount; there are different sales price values.
