Number of girls at the time of the assembly started = w
Number of girls left = 40% of w
Remaining girls = 
Now, the ratio of the number of boys to girls became 3 to 4.
Let n be the number of boys.
Then, 
Or, 
20n = 9w
or, n = 
Total number of boys and girls = 
Hence, the total number of boys and girs is 
Answer: $135
Step-by-step explanation: 48% of $355 would be 170 so therefore the $135 would be the cheaper penalty
Answer:
x^2 - 9
Step-by-step explanation:
length = 2x - 6 = 2(x-3)
Area = [2(x-3) * (x + 3)]/2 = (x-3)(x+3) = x^2-9
We have 8 dozen bagels, or 8*12=96 bagels. Each plate can hold 14 bagels, so we have enough bagels to fill 96/14=about 6.86 plates. However, we cannot have a fraction of a plate, so we round up to have a total of seven plates. To fill all seven plates fully, 7*14=98 bagels would be needed, which is two more than we have.
To summarize, Mr. Corsetti has seven plates of bagels, and would need two more bagels to fill the last one up.
