What are the equations for this question? how do you answer it?
Digiron [165]
Because we are looking at money and amount there will be 2 sepret equations that can be solved using the Elimination or Substitution method.
$4,800=x18+y33 would be the first one that is dealing with money.
200=x+y

I personally find the substitution method easier but whatever you like could work. First things first, get Y alone in ONE equation, you can choose whatever one you want but I am going to use the bottom one cause it is the easiest.

200=x+y
-x -x subtract x from both sides
200-x=y. y is now alone making it easy to switch the equation
y=200-x this equation is the value of y

Now plug in the value of y in the top equation,

4,800=x18+33(200-x) now solve this equation

4,800=x18+6600-33x
4,800=-15x+6600
-6600. -6600
-2200=-15x. divide by -15
x=146.67

now since we have the x value we can plug it in to the bottom equation.

200=146.67+y
-146.67
y=53.33

these coordinates are the intersection point so it'll give ya the number.

hope this helped a little

Ken spent 1/5 of his allowance on a movie, 3/8 on snacks, and 2/7 on games. If his allowance was $20, how much did Ken have left
Lisa [10]
1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07

Answer: $6.07 is the amount ken has remaining
