Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
= 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
= 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
= 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3

Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8

Answer:
is in slope intercept form
Step-by-step explanation:
We need to write the equation in slope intercept form
Slope intercept form of the equation is
where m is the slope and b is the y intercept
To get the equation in slope intercept form we need to get y alone
Multiply 1/2 inside the parenthesis
To get y alone , subtract 5 from both sides
is in slope intercept form
If y+6=15, then y=9. (9+6)divided by 3 would be 5, not 15.
