Answer:
(-1,0)
Step-by-step explanation:
C = children
a = adults
12c + 15a = 33456 (price)
c + a = 2450 (people)
c = 2450 - a (rewrite^)
12(2450 - a) + 15a = 33456 (substitute into the price equation)
29400 - 12a + 15a = 33456
3a = 4056
<u>a = 1352
</u>c = 2450 - (1352)
<u>c = 1098</u>
1098 children
1352 adults
Formula for area of a trapezoid = a+b/2*h (a and b being the two bases, in this case 38 and 18, and h being height)
Plugging in the bases and height, this turns into 38+18/2*16
38+18=56
56/2=28
28*16=448 square centimeters
