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?
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.
To find Mike's profit when he sells 4 tables, we need to subtract his upfront costs from the amount of money he earns making custom tables.
Let's substitute the value of × with 4 and solve the expressions step by step.
First, we have the expression 60% + 4, which represents the amount of money Mike earns making custom tables.
Substituting × with 4, the expression becomes: 60% * 4 + 4.
Calculating 60% of 4 is 0.6 * 4 = 2.4, so the expression simplifies to: 2.4 + 4 = 6.4.
Now, let's move on to the expression 2x - 4, which represents Mike's upfront costs.
Substituting × with 4, the expression becomes: 2 * 4 - 4 = 8 - 4 = 4.
To find Mike's profit, we subtract his upfront costs from the amount of money he earns:
Profit = Amount earned - Upfront costs
Profit = 6.4 - 4
Profit = 2.4
Therefore, Mike's profit when he sells 4 tables is 2.4.
