We need to plug in x=4 into both expressions and then subtract the upfront costs from the earnings to find the profit.
Earnings = 60% + 4 = 0.6x + 4 (where x=number of tables sold)
Plugging in x=4: Earnings = 0.6(4) + 4 = 6.4
Upfront costs = 2x - 4
Plugging in x=4: Upfront costs = 2(4) - 4 = 4
Profit = Earnings - Upfront costs = 6.4 - 4 = 2.4
Therefore, Mike's profit when he sells 4 tables is $2.40.
The expression 60% + 4 represents the amount of money Mike earns making custom tables. The expression 2x - 4 represents his
upfront costs. If × represents the number of tables sold in both expressions, what is Mike's profit when he sells 4 tables?
