The Lamar Company manufactures wiring tools. The company is currently producing well below its full capacity. The Boston Company has approached Lamar with an offer to buy 10,000 tools at $1.75 each. Lamar sells its tools wholesale for $1.85 each; the average cost per unit is $1.83, of which $0.27 is fixed costs. If Lamar were to accept Boston's offer, what would be the increase in Lamar's operating profits

Cost per unit = $1.83

Variable cost  = Total cost per unit - Fixed cost per unit = $1.83 - $0.27 = $1.56

Marginal Contribution per unit = Selling price - variable cost = $1.75 - $1.56 = $0.19

Total addition to operating profit = $0.19 x 10,000 = $1,900

you have to put the parentheses like this:

in fact, you have to perform the operation inside parentheses first, and then proceed in order:
