Answer:
48 uniforms
Step-by-step explanation:
1836-612=1224.
1224/25.50=48.
Checked answer:
25.50 x 48= 1224
Use substitution
Set them equal to each other
-3x + 4 = 3x - 2
Solve the equation
4 = 6x - 2
6x = 6, x = 1
Plug in 1 for any equation to find y
Y = -3(1) + 4
Y = -3 + 4, y = 1
Solution: x = 1, y = 1
Answer:

Step-by-step explanation:
<u><em>The question is</em></u>
Which equation should she use?
we have the formula

Solve for k
That means ----> isolate the variable k
Multiply by 2 both sides

Divide by x^2 both sides

Rewrite

Let p = her pay per week.
<span>"Karissa earns $200 per week plus $25 per item she sells."
She earns a fixed amount of $200 per week no matter how much she sells.
Then she earns an additional variable amount that depends on the number of items she sells. It is $25 per item.
p = fixed amount + variable amount
The variable amount is:
If she sells 1 item, she earns 25 * 1
If she sells 2 items, she earns 25 * 2
If she sells 3 items, she earns 25 * 3
If she sells n items, she earns 25 * n
The variable amount she earns is 25n, where n is the number of items she sells.
</span>
<span>p = fixed amount + variable amount
p = 200 + 25n

Let initially number of fishes =x
He gives 2/3 of his fish to a local high school, that is he gives 2x/3 fish .
So number of fishes left = x -(2x/3) = x/3 . And he gives 2/5 of x/3 to an elementary school , that is , he gives 2x/15 fishes to the elementary school. And finally the number of fishes left =30 , that is




So initially he have 150 fishes .
