ANSWER
8x + 3y = 2000
x => The number of adults
y => The number of children
EXPLANATION
Let the number of adults be x.
Let the number of children be y.
Each adult will be charged $8 admission. This would mean that the charges for x adults will be:
8 * x = $8x
Each child will be charged $3 admission. This would mean that the charges for y children will be:
3 * y = $3y
The club wants to earn $2000 from admission charges. This means that adding the total charges for adults and children should yield $2000.
Therefore, we have:
8x + 3y = 2000
The variables are:
x => The number of adults
y => The number of children
You isolate for x. Meaning that x remains on the left side BY ITSELF all alone, in order to do that, you must bring - 13 to the RIGHT side of the equation. When you bring -13 to the right side you have to change it’s sign, so -13 will become +13.
X=37+13
X=50
X is 50
To find the area of the circle use the A = πr²
r (or radius) = 1.5
Plug in 1.5 for r
A = π(1.5)²
Square 1.5
A = π(2.25)
A = 2.25π yd² is your answer
hope this helps
