16) s = 38, b = 36

Number of golds won by US = 36 (first graph)
Number of total medals won by US: 110 (second graph)
Number of bronze and silver medals = 110 – 36 = 74 medals
If gold (g) = 3, silver (s) = 2 and bronze (b) = 1
US has a score of 220
We can get the following equation:
3g + 2s + 1b = 220
(36 x 3) + 2s + 1b = 220
2s + 1b = 112

We know that s + b = 74
Using simultaneous equations, we get:
2s + 1b = 112
s + b = 74

s = 38
Since s + b = 74, b = 36

s = 38
b = 36
