How to solve???????????
Soloha48 [4]

Answer:

$70.88

Step-by-step explanation:

To find sales tax, multiply the price by the percentage as a decimal.

$67.50                         67.50(0.05) = $3.38

Since sales tax is 5%, its decimal equivalent is 0.05 and for the price of $67.50 you pay $3.38.

The total amount paid is the price added to the sales tax.

$67.50 + 3.38 = $70.88

Repeat these steps for each price in the sales amount column.

Need help on this problem <br> Multiple questions
umka21 [38]

answer: a. input, output

explanation: this is because the x values can not repeat in a function. if they do, they would not pass the vertical line test, and therefore it would not be a function. so, each input and output must be different values. :)
