Hello,

You have just to read the arrows un reversed order:
in f we find (-1,-3) so in f^{-1} we find (-1,-3)^{-1}=(-3,-1)
2a + 3p = 1.59
a = 0.24
Plug it in our equation:
2(0.24) + 3p = 1.59
Multiply:
0.48 + 3p = 1.59
Subtract 0.48 to both sides:
3p = 1.11
Divide 3 to both sides:
p = 0.37
So one pair costs <span>£0.37</span>
