g(x)= 3k-2x²

g(-3)=-6 ____(1)

So, using (1),

-6 = g(-3)

=> -6 = 3k - 2(-3)²

=> -6 = 3k - 2(9)

=> -6 = 3k - 18

=> -6 +18 = 3k

=> 12 = 3k

=> 12/3 = k

=> 4 = k

Now, you can find g(n) for any number n, as now we know the value of k. Specify the value of x, if you want to know what is g(x).

ioda

$225 was earned from the craft sales

and $40 was earned from the play.

Given, During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play admissions.

Of each dollar earned, $0.15 came from games. Craft sales earned 3 times as much as games. Food sales were 4 times the amount earned from the play.

Let the amount earned by play be x,

Also, crafts earned 3×75 = $225

Now, as play earned x, then food earned 4x.

According to question,

x + 75 + 225 + 4x = 500

5x + 300 = 500

5x = 200

x = 40

So, the amount earned by Play be, $40

and the amount earned by Food be $160.
