Gregory predicts that 310 people will attend the spring play. There was an actual total of 220 people who attended the spring play. What is the percent error?

1550 instead of 1100

Step-by-step explanation:

20% of 1100 = 220

20% of 5500 = 1100 and then he went back and changed 5500 to 1550 and found 310.

20% of 1550 is 310

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
