Answer:
15 action figures
Step-by-step explanation:
Jacob had $200 to start off with. He spent $75 on vehicles, so we are going to subtract $75 from $200
200 - 75 = 125
He had $125 left. From the money he has left, he wants to purchase more toys. Action figures are $8 each. We will need to find how many action figures he can buy with the rest of his money. To do that, we will divide $125 by $8
125/8 = 15.625
He can buy 15 action figures with his remaining money. He will have remaining change.
I think the equation is:
8x + 125 = 200
8 gets the variable, 200 is the total, and 125 will not get the variable.
There are four possibilities...but first does the problem tell you how many total fish were sold?
If not the possible combinations are:
0 angel and 9 clownfish
2 angel and 6 clownfish
4 angel and 3 clownfish
6 angel and 0 clownfish
4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
