Question

Celia buys 1 fish and 2 portions of chips.

The total cost is £5.60

Celia and Dave share the £5.60 cost in the ratio 4 : 3

Work out how much Celia pays and how much Dave pays.

Answer 1

Cecilia=£3.20

Dave=£2.40

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}* 5.60\\\\=\£3.20\\\\Dave=Total- Cecilia's\\\\=5.60-3.20\\\\=\£2.40`

Hence,Cecilia pays £3.20 and Dave pays £2.40
