Marcus estimates that 230 people witll attend the choir concernt. the actual total that attended was 300 people. find the percent error

Your percent error is the difference of the estimated value and the accepted value divided by the accepted value, then multiplied by 100. So it would be (230-300)/300)x100, which would be (-70/300)x100 which then equals a -23.3% error

Hold on lemme do the work
