Lydia guessed there were 180 jelly beans in a container. There were actually 220 jelly beans in the container.
What was Lydia's percent error?

18.18% error

Step-by-step explanation:

Use the percent error formula,

% error = | (measured - accepted) / accepted | x 100

Plug in the values we know:

% error = | (180 - 220) / 220 | x 100

% error = | - 0.18 | x 100

% error = 18.18% error

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
