Isaiah buys produce for a local restaurant. He spent $2.80 to buy 3 pounds of tomatoes and

cost per lb of tomatoes is $0.80 and cost per lb of oranges is $0.10

Explanation: let x = cost per lb of tomatoes;let y= cost per lb of oranges;3x+4y=2.80 4x+2y=3.40 solve the system by elimination:3x+4y= 2.80 -8x-4y = -6.80,add them up :-5x= -4.00, x=0.80;plug in x in any equation snd solve for y,and y= 0.10
