Latex 凭证预算约束tikz

我从超级有用的指南中获取了以下代码，并在TeXstudio中运行它

 [domain=0:5,range=4:5,scale=1,thick]
    \usetikzlibrary{calc}%all
    %Definelinearparametersforsupplyanddemand
    \def\inc{62}%Entertotalincome
    \def\pa{19.5}%Priceofx1
    \def\pb{10}%Priceofx2.
    \def\panew{10.6}
    \def\ica{\x,{2/\x−20}}
    \def\icb{\x,{\sslp∗\x+\sint}}
    \def\bcv{\x,{(−\pa)/(\pb)∗\x+(\inc)/(\pb)}}
    \def\bcx{\x,{(5)/\x}}

    %Definecoordinates.
    \coordinate(x2)at(0,{\inc/\pb});
    \coordinate(x1)at({\inc/\pa},0);
    \coordinate(x1’)at({\inc/\panew},0);
    %Drawaxes,anddottedequilibriumlines.
    \draw[->](0,0)(6.2,0)node[right]{$x1$};
    \draw[->](0,0)(0,6.2)node[above]{$x2$};
    \draw[dashed](1.2,3.9)(0,3.9)node[left]{voucher};
    \draw[thick,domain=1.2;\inc/\pa]plot(\bcv)node[below]{BudgetConstraint};
    \draw[thick,color=purple,domain=1:5]plot(\bcx)node[below]{Indiff.Curve};

它应该是这样的：

但我有一个错误：

Paragraph ended before \tikz@plot@samples@recalc was complete.

\begin{abstract}
Mental accounting, a form of bounded rationality, is an influential theory of microeconomic behaviour. It has only recently been shown to play a significant role in distorting private consumption decisions and its predictions are strong. Fieldwork has shown that consumers experience inframarginal in-kind donations as distortionary, which violates the predictions of the standard model. This paper extends applies this body of research to private donations. Integrating the two literatures, I test whether mental accounting is a neglected alternative to ‘warm glow’ in explaining patterns of private donation which deviate from a model of pure altruism. A randomised controlled trial run on undergraduate students provides new evidence that mental accounting is responsible for this pattern of donation.
