If it’s only 7 ppl you would have to double the amount of people meaning that 14 people shook each other’s hands but not quite cause they shook each other’s hands 7•14=98/4=25

Answer:

-2

Step-by-step explanation:

Subtracting a negative number is the same as adding it, so this is basically just negative 8 plus 6, which is -2. Don't know who was right though, you kinda left that part of the question out.

The tax rate as a percent, r, charged on an item can be determined using the formula – 1 = r, where c is the final cost of the i
melisa1 [442]

The <em><u>correct answer</u></em> is:

$43.20

Explanation:

The formula we have is

c = p(1+r), where c is the total cost, p is the price of the item before tax, and r is the tax rate written as a decimal.  This formula comes from the fact that adding a percent tax to the cost of an item takes 100% of the price and adds r% to it; this is why we multiply the price by (1+r).

Since our tax rate is 8%, r = 8% = 8/100 = 0.08.  The price of the item is $40.  Using this information, we have:

c = 40(1.08) = $43.20
