Question

Earl earned $11.50 less than Kay. Trinity earned $15 more than 3 times the amount Kay earned. Earl, Trinity, and Kay earned $336 in all. How much money did Earl earn?

a) $120.50
b) $125.50
c) $115.50
d) $110.50

Answer 1

Earl earned $55. None of the options is true.

Explanation:

Let's denote the amount Kay earned as "K".

According to the problem, Earl earned $11.50 less than Kay, so Earl earned K - $11.50.

Trinity earned $15 more than 3 times the amount Kay earned, which can be expressed as 3K + $15.

The total amount earned by Earl, Trinity, and Kay is $336. We can set up an equation to represent this:

K + (K - $11.50) + (3K + $15) = $336

Combining like terms, we get:

5K + $3.50 = $336

Subtracting $3.50 from both sides, we get:

5K = $332.50

Dividing both sides by 5, we find:

K = $66.50

Therefore, Earl earned $66.50 - $11.50 = $55.

Thus, None of the options is true.
