Ksju [112]

Answer:

$d = m + 10\\d+m=150$

Step-by-step explanation:

If Avery wants the amount of dark chocolate (d) to be 10 kg higher than the amount of milk chocolate (m), then the following relationship must be true:

$d = m + 10$

If the total amount of chocolate must equal 150 kg, then:

$d+m=150$

The system of equations that represent this situation is:

$d = m + 10\\d+m=150$
