Answer:

1.40 $ per pound.

Step-by-step explanation:

As we go by the statement given:

$2x + 3y = 7.20 ..... (1) \\and\\4x + 2y = 8.80 ...... (2)\\\\Now, multiplying \ the\ equation \ (1)\ by\ 2\ and\ then\ subtracting\ the\ equation\ (2)\ from\ it.\\(1) \times 2\\ \Rightarrow 4x+ 6y=14.40\\Now, subtracting\ the\ equation\ number (2)\\ \Rightarrow4x + 6y - 4x -2y = 14.40 - 8.80\\\Rightarrow 4y = 5.60\\\Rightarrow y = 1.40$ Hence, price for oranges is $1.40$ dollars per pound.
