A raffle is being held to benefit the local animal shelter. They sell 717 tickets that do not win any prize, 19 tickets that win
matrenka [14]
Let’s start by finding the total amount of tickets sold

717+19+1=737

Now multiply by 5 to see how much money they initially brought in

737•5=3,685

Now let’s find the total expense of the prizes

166+(19•20)=t

166+380=546


Now subtract the expenses from the total ticket sales

3,685-546=3,139


They made $3,139 TOTAL


Now let’s divide the total made by the total tickets sold

3139 / 737 = 4.26


They made $4.26 PER TICKET


Hope this helps!

If you were to add 5 to my number and then divide by 4, you would get 7
Norma-Jean [14]
Let's make an equation. T will be the number.
(T+5)/4=7
Let's multiply both sides by 4 to get T by itself.
T+5=28
Subtract 5 from both sides.
T=23
Your number is 23.

If an original conditional statement is represented by p → q, which represents the contrapositive?
Maksim231197 [3]

<span>A conditional statement has two parts, the hypothesis and the conclusion. In p and q notation, the hypothesis is always the p and the q is the conclusion. In a contrapositive statement, the statement would go, “if not q, then not p”. Therefore, the answer to this item is the second choice.  </span>
