Cecilia=£3.20

Dave=£2.40

Step-by-step explanation:

-The sum of the ratios is:

$\sum{Ratios}=4+3\\\\=7$

#To find out how much each pay, your multiply the individuals ratio divide by the sum of the ratios times the cost;

$Cecilia=\frac{4}[7}\times 5.60\\\\=\£3.20\\\\Dave=Total- Cecilia's\\\\=5.60-3.20\\\\=\£2.40$
