Question

The expression 60x + 4 represents the amount of money Mike earns making custom tables. The expression 2x − 4 represents his upfront costs. If x represents the number of tables sold in both expressions, what is Mike's profit when he sells 4 tables?

$8
$240
$61
$244

Answer 1

$240

Explanation:

To find Mike's profit when he sells 4 tables, we need to subtract his upfront costs from his earnings for selling those 4 tables.

The earnings for selling 4 tables can be found by plugging in x = 4 into the expression 60x + 4:

60(4) + 4 = 240 + 4 = $244

So Mike earns $244 for selling 4 tables.

The upfront costs for selling 4 tables can be found by plugging in x = 4 into the expression 2x - 4:

2(4) - 4 = 8 - 4 = $4

So Mike's upfront costs for selling 4 tables is $4.

To find his profit, we need to subtract the upfront costs from his earnings:

Profit = Earnings - Upfront Costs

Profit = $244 - $4

Profit = $240

Therefore, Mike's profit when he sells 4 tables is $240. Answer: $240.
