If 3 apples and 4 bananas cost 1.37 total and 5 apples and 7 bananas cost 2.36 total what is the total cost of 1 apple and 1 banana?

Let $x and $y be the cost of an apple and a banana respectively
3x+4y=1.37(1)
5x+7y=2.36(2)
(1)*5, 15x+20y=6.85(3)
(2)*3, 15x+21y=7.08(4)
(4)-(3), y=0.23
sub. y=0.23 into (1), 3x+4*0.23=1.37
                                 x=0.15
total cost=0.15+0.23=0.38

Well is there a picture

The answer would be c.hope this .
