$.75 :)

anonymous · Answer

$0.75 (EACH ORANGE) *6oranges= $4.50
$5.60-$4.50= $1.10
$1.10/2 apples= $0.55 EACH APPLE

$0.55*6apples= $3.30
$4.80-$3.30= $1.50 (MONEY LEFT)
$1.50/2oranges= $0.75

ANSWER: C, $0.75

@EmmaH  medal?

anonymous · Answer

2(a) + 6(o) = 5.6          6(a) + 2(o) = 4.8

Multiply the first equation by -3

-6(a) - 18(o) = -16.8        6(a) + 2(o) = 4.8

Add the first equation to the second:

                                          -16(o) = -12

Solve for "o":

                                                 o = 0.75

That very last step is gotten by dividing both sides by "-16".
