Question

Three apples and 2 oranges cost $1.25, while 2 apples and an orange were 75 cents. At the rate, find the cost of 6 apples and an orange. ( please show steps thanks!)

Answer 1

x - apple
y - orange


`3x+2y=1.25\\ 2x+y=0.75\\\\ 3x+2y=1.25\\ -4x-2y=-1.5\\ --------\\ -x=-0.25\\ x=0.25\\\\ 2\cdot0.25+y=0.75\\ 0.5+y=0.75\\ y=0.25\\\\ 6x+y=6\cdot 0.25+0.25=1.5+0.25=\boxed{1.75}`
