So there are 50 teens total
16% have no sibblings
so we must find 16% of 50
16%=16/100=0.16
'of' can be translated as multiply so
0.16 times 50=8
there were 8 teens who have no sibblings
Answer:
It's no answer. This question is unsolvable

Answer:
£56.25
Step-by-step explanation:
Number of guest = 57
The 20cm cake :
Can serve 12 people and cost £13.50
The 25cm cake :
Can serve 20 people and cost £18.75
Since the cake has to be the same size, the only one particular size would have to be purchased ;
For the 20cm cake ; 57/12 = 4.75 = five 20cm cakes ;
£13.50 * 5 = £67.50
For 25cm cake ; 57 / 20 = 2.85 = three 25cm cakes
£18.75 * 3 = £56.25
£56.25 is lower ; hence, amount he'll have to pay is £56.25
