x^2 = 1500 /15
x = 
x = 10

Answer:
5 cakes
hope it helps
Step-by-step explanation:
if one cake feed 14 people and you are tying to fine out how many cakes you need to feed 60 people you would have to divide 60 by 14
1 cake = 14 people
? cakes = 60 people
60 ÷ 14 = 4.28
so in order to have enough for 60 people you need to round so you would need 5 cakes
to check you answer you can multiply 5 by 14 and you answer should be the amount of people
5 x 14 = 70
why cant it be 4? well because if you buy 4 cakes there wont be enough for 60 people and to make sure it wont be enough you can multiply 4 x 14
4 x 14 = 56
so 4 cakes only feeds 56 people so that is why your answer is 5 cakes are needed
