Answer:

0.923

Step-by-step explanation:

There are 13 total marbles. (12 Purple Marbles + One Blue Marble)

The total events are 13 and the number of preferred events is 12.

\frac{12}{13}= 0.92307692307 ≈ 0.923

So there should be a 0.923 chance that a purple marble is picked.

A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwich
valkas [14]

Answer:

513 turkey sandwiches were sold.

Step-by-step explanation:

Let's use x to represent turkey sandwiches and y to represent steak sandwiches.

x = turkey sandwiches

y = steak sandwiches

x + y = 925 total sandwiches that were sold

4x + 6y = 4524 dollars that were made

x + y = 925\\y = 925 - x

Now that we know what y (steak sandwiches) equals, we plug it in to an equation to find x.

4x + 6(925-x) = 4524\\4x + 5550 -6x=4524\\

Now, we subtract 5,550 from BOTH sides so we can get x by itself.

-2x + 5550 - 5550 = 4524 - 5550\\-2x = -1026

Next, we divide both sides by 2, so x is bare.

\frac{2x}{2} = \frac{1026}{2}

x = 513

Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.

I hope this helps! :)
