Manoel tests his aim by launching five arrows that hit the target at points $A, B, C, D$ and $E$, with coordinates $A=(1,-1), B=(2.5, 1), C=(-1,4)$, $D=(-4,-4)$ and $E=(6,5)$.

The table shows how many points are earned when an arrow hits a point within each of the three regions, as shown in the figure.

(a) Mark the points $A, B, C, D$ and $E$.

(b) How many arrows did he hit inside the smallest circle?

(c) In total, how many points did Manoel score?

(a) The five given points are marked in the figure.

(b) In the smaller circle, we have only point $A$, so Manoel hit this circle once, which gives him 300 points.

(c) To calculate the total points, observe that for point $B$ he earns 100 points, for $C$ he earns 50 points, and for $D$, 50 points. However, for point $E$, he does not earn any points because it is outside the scoring zone. Therefore, the total number of points Manoel scored is $300+100+50+50=500$.
