The model overestimates the percentage by $0.8$ percent.
Substituting a with 24 in the given formula, we find $p=52-0,3\cdot a$ $p=52-0,3\cdot 24$ $=52-7.2$ $=52.0-7.2$ $=44.8$ (percent) The graph gives $44=44.0$, so the model overestimates the value in the graph by $0.8$ (percent). $(44.8-44.0=0.8)$ The model overestimates the percentage by $0.8$ percent.
