You randomly survey students about year-round school. the results are shown in the graph.
a bar graph shows the percent of students who favor or oppose year-round school. the percent who oppose is 68 percent. the percent who favor is 32 percent. the error is plus or minus 5 percent.
the error given in the graph means that the actual percent could be 5% more or 5% less than the percent reported by the survey.
a. write and solve an absolute value equation to find the least and greatest percentages of students who could be in favor of year-round school. use $x$ as the variable in the equation.
