question: Sandra's neighbor gives her a basket of 9 eggs every time she babysits their daughter. To make a Spanish flan, she needs 3 eggs. If Sandra has been tasked to make 15 Spanish flans for her school fundraiser, how many times does Sandra have to babysit?
answer: Sandra needs a total of 15 x 3 = <<15*3=45>>45 eggs.
  She will have to babysit 45/9 = <<45/9=5>>5 times.
