Question

A school staff meeting had 80 teachers is attendance, 30 percent of whom were first year teachers. How many teachers at the meeting had taught for more than one year?

Answer 1

Since only 30% of the teachers taught for one year, the remaining percentage of the teachers had taught for more than a year, or 70%.
70%=0.7
80(0.7)=56
56 teachers had taught for more than a year.
