Paul receives 2 portions, which equals to 7.9 * 2 = 15.8
Colin receives 3 portions , this equals to 7.9 * 3 = 23.7
the difference between the 2 portions is 23.7 - 15.8 = 7.9
hence, Colin receives £7.9 over Paul

Answer:
The measure of the angles:
24° and 66°
Step-by-step explanation:
Complementary angles sum 90°
then:
(3x + 3) + (10x-4) = 90
3x + 10x + 3 - 4 = 90
13x - 1 = 90
13x = 90+1
13x = 91
x = 91/13
x = 7°
then:
3x+3 = 3*7 + 3 = 21+3 = 24°
10x - 4 = 10*7 - 4 = 70 - 4 = 66°
Check:
66° + 24° = 90°
