What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:
[(5.4*3+5)+(8+3.2*3)]/2
= (21.2+ 17.6)/2
= 38.8/2
= 19.4

The average of the two boys' points is p=3 is 19.4 points~

Let d be the number of days and h be the height

h = 13 + 0.6d

Answer: (a) h = 13 + 0.6d

Given height = 0.208m, find d:

0.208m = 20.8 cm

20.8 = 13 + 0.6d

0.6d = 20.8 - 13 = 7.8

d = 7.8 ÷ 0.6 = 13
