Answer:
Step-by-step explanation:
2c+12t=105, and 5c+3t=33, subtracting 4 times the second from the first gives you
2c+12t-20c-12t=105-132
-18c=-27 dividing each side by -18
c=1.5, making 2c+12t=105 become
2(1.5)+12t=105
12t=102
t=8.5
So each chair costs $1.50 and each table costs $8.50
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
