The theater arts committee estimated that it would sell 200 tickets for its upcoming play. The committee actually sold 224 tickets. What was the percent error in the committee’s estimate? Round your answer to the nearest tenth of a percent.

Answers

Answer 1
Answer:

First, subtract the estimated tickets that will be sold from the actual tickets sold. 200 – 224 = -24, ignore the negative sign, so the error is 24. Then, divide the error by the actual ticket sold, 24/224= 0.1071 and multiply the answer by 100 to get the percentage. So, the percentage error is 10.7%.

please solve

Answers

-43x + 16 < 79

Subtract 16 from both sides, 
-43x < 63

x < -63/43

Hope this helps!

-43x + 16 -16< 79 -16;   -43x ÷ -43 < 63 ÷ -43; x > -1.47
