$124.
Jason- 20$ more than Darcy
Maria- Twice as much as Jason
Darcy- 20$ less than half of Maria's sum.
After I had written the page below, I came back up here and realized there was a much easier way.
268/2 = 134
Since the 20 Is added after, half is subtracted and you end up with
124!!
Now for my explanation done first, typed and read as I figured it out.
First and mostly, we need to find what Darcy starts with.
Let's say that Darcy has 5 dollars, to start somewhere easy. That would mean that Jason has 25 dollars since he has 20 more than her. That would mean that Maria would have 50 dollars, and the looted sum is 80.
Since that is less than a quarter of our end goal of 268$, I raised Darcy's initial amount of money to 15 to triple her money.
Math revised here- 15+20= (35*2) 70= 120
15+35+70
Since that is too low, I'm adding it to 30$.
Math revised again here- 30+20=(50*2)=100= 180
30+50+100
5 15 30
80 120 180
That is a chart determining our answers so far. There is no clear pattern, so let us continue.
Darcy starts with 50 dollars for this one.
50+20=(70*2)=140
50+70+140
260.
We are close to the sum.
Darcy starts with $52
52+20(72*2)= 144
52+72+144
268!
This means we have found how much Darcy has, and since Jason's amount depends on her, we have found both of their sums!
Answer:
11.98
Step-by-step explanation:
Answer: C. 1/25
Step-by-step explanation:
P(A) = favorable outcomes / possible outcomes
P(A and B) = probability of A * probability of B
P(tomato) = 2/10
P(cheese) = 2/10
P(tomato and cheese) = 2/10 * 2/10 = 1/25
Answer:
1/5
Step-by-step explanation:
You have 10 cans in all and the chance of pulling a can of tomato soup is 2/10 since there are two cans of tomato soup. simplifying 2/10 is 1/ 5. The same goes for the cheese soup. 10 cans two of them are cheese so you have 2/10, which simplify into 1/5

Answer:
Preston has 19 games and Horatio has 30 games
Step-by-step explanation:
This problem is solved by a system of equations. First, the variables are defined:
p: Preston video games
h: Horatio video games
It is known that between them they have 49 video games, that is to say that between them they add 49 games. So the first equation is p+h=49.
On the other hand, it is known that Horatio has 11 video games more than Preston. This means that h=p+11
So, now you have the system of equations. To solve it, there are several methods. In this case the substitution is used, which consists on isolate a variable in one of your equations and replacing on the other equation.
In this case, you have an isolated variable: h=p+11. By replacing it in p+h=49, you get: p+p+11=49
Now you have an equation with a variable, which can be solved:
2*p+11=49
2*p=49-11
2*p=38
p=19
This means that Preston has 19 video games.
Now you have to determinate how many video games have Horatio. For that you know that h=p+11, and you knwo the value of p. Simply replacing you get the value of h
h=p+11
h=19+11
h=30
This means that Horatio has 30 video games.
