<human>:  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?
<bot>: How many eggs does Sandra need? ** Sandra needs a total of 15 x 3 = <<15*3=45>>45 eggs.
How many times does Sandra have to babysit? ** She will have to babysit 45/9 = <<45/9=5>>5 times.
