Answer:
(a) variable: $6.10; fixed: $9,310
(b) break-even: 1900 haircuts; $20,900 sales
(c) net income: $2,548
Explanation:
(a) The fixed costs are anything not given as "per haircut." Their total seems to be ...
fixed expense = 5×1480 +510 +220 +980 +180 +20 = 9310
variable expense = 5.50 +0.36 +0.24 = 6.10
Variable costs per haircut are $6.10; monthly fixed costs are $9,310.

(b) The break-even point will be the number of haircuts that makes revenue equal to expenses. If that number is represented by n, revenue is 11n and expenses are 6.10n+9310. Solving for n, we find ...
11n = 6.10n +9310
4.90n = 9310 . . . . . . subtract 6.10n
n = 9310/4.90 = 1900 . . . . . . . haircuts to break even
11n = $11·1900 = $20,900 . . . break-even sales

(c) We found in part (b) that each haircut contributes $4.90 to net income. So, the profit from 2420 haircuts will be the contribution margin for all of those haircuts that are more than the 1900 required to pay fixed expenses.
$4.90 × 520 = $2,548 . . . . net income
