Answer:

£1.31

Step-by-step explanation:

5+7+12=24

216÷24=9

Small=9x5=45

Medium=9x7=63

Large=9x12=108

2x= Medium, Large= 3x, Small=x

Small=45x, Medium= 63x2=126x, Large=108x3=324x

45x+126x+324x=495x

£648.45=495x

£648.45÷495=x

£1.31=x

The profit for one small cake will be £ 1.31. The profit of the one small cake is the amount of benifit obtained to sell one cake.

What is profit?

When money generated from a commercial activity exceeds the expenses, costs, and taxes involved in maintaining the activity in question, profit is earned.

The ratio of the small :medium: large cake is 5:7:12.

Let the cake is considered to be x;

The sum of alll the cakes is;

5x+7x+12x=24 x

The total no of cake is 216

Each no of cake is found as;

[tex]\rm 24 x = 216 \\\\ x = 9[/tex]

The number of the small cake;

N(s) = 9 ×5 =45

N(m)=9×7=63

N(l)=9×12=108

Let the small cake is x

The profit for one medium cake is twice the profit for one small cake;

P(m)=2x

P(l)=3x

P(s)=x

The small medium and the large cake according to the new condition will be 45 x,126x,324x respectively.

The sum of all the cakes according to the new condition is found as;

[tex]4s x +126 x+324 c \\\\ 495 x=648.45 \\\\ x=\£ \ 1.31[/tex]

Hence the profit for one small cake will be £ 1.31.
