Answer:
82 adults 317 children
Step-by-step explanation:
c= children
a = adults
A) a+ c = 399
B) 1.25(c) + 2.50(a) = 601.25
Multiply the whole A) by -1.25
Add A) +B) (c will be eliminated since 1.25c -1.25c=0)
-1.25 c - 1.25a = -498.74
1.25 c+ 2.50 a = 601.25
1.25 a = 102.50
Divide both sides by 1.25:
a = 82 (82 adults)
399-82 = 317 (317 children)
317 ($1.25) = $396.25 Price for 317 children
82($2.50) = $205 Price for 82 adults
Total:
$ 396.25 + $205 = $ 601.25
317 + 82 = 399
c =
