Answer 1

Step-by-step explanation:

step 1:

total profit /sum of raitio

648/24=27

2nd step:

ratio*per cake profit

27*5=135

step3:

7*27=189

step 4

12*27=324

so sum of total profit =648

so a small cake profit is 135. I hope that is right answer.

Answer 2

Answer: £1.31

Step-by-step explanation:

5+7+12= 24

216÷24= 9

small = 9×5= 45

medium = 9×7= 63

large = 9×12= 108

small = x

medium = 2x

large = 3x

small = 45x

medium = 2(63)x= 126x

large = 3(108)x= 324x

45x+126x+324x= 495x

£648.45= 495x

£648.45÷495= x

x= £1.31
