C = children
A = adults
293 = c + a
1.50c + 2.50a = 676.50
We can use substitution to solve:
c + a = 293 subtract a to get c = 293 - a
Plug this into the second equation:
1.50(293 - a) + 2.50a = 676.50
439.5 - 1.50a + 2.50a = 676.50
439.5 + 1a = 676.50
a = 237
Substitute this into the first equation:
293 = c + 237
56 = c

<h2>
c = d/a - b</h2>
Step-by-step explanation:
1. Divide each term by "a," and simplify.
c + b = d/a
2. Subtract "b" from both sides of the equation.
c = d/a - b
