Answer:

Step-by-step explanation:

The prices are inconsistent, so there is no unique price that can be set for either an apple or an orange that will give the total prices indicated.

The first relation can be written as ...

$10 = 4A +4O

$10 = 4(A +O) . . . . factor out 4

$2.50 = A +O . . . . divide by 4

The second relation can be written as ...

$12 = 6A +6O

$12 = 6(A +O) . . . . factor out 6

$2 = A +O . . . . . . . divide by 6

These two relations give different prices for 1 apple and 1 orange. There is no price that can be set for either fruit that will give this result.

No unique prices can be assigned.
