Answer 1

C(x) = 134 + 0.78

Explanation:

Let

x = number of drinks they made

Total cost, C(x) = fixed cost + variable cost

Fixed cost = $134

Variable cost = additional cost per drink * number of drinks

= 0.78 * x

= 0.78x

C(x) = 134 + 0.78

They sell each drink = $3.50

Total revenue, R(x) = sale price of each drink * number of drinks

= 3.50 * x

= 3.50x

R(x) = 3.50x
