please help me to understand this question

2. Your client's second child is planning to study a four year Bachelor degree in Physiotherapy when she graduates from high school, 7 years from now. She anticipates that she will need $10,000 at the beginning of each of her four years of university to pay for tuition fees and study expenses and have some spending money. She has made an arrangement with your client to do the household chores if your client deposits $3,500 at the end of each year, for the next 7 years in a bank account paying 8% interest p.a. Will there be enough for your client's daughter to pay her university expenses? If there is not enough, how much does your client need to deposit at the end of each year in order to provide sufficient funding for her daughter's university education? Assume the rate of interest stays at 8% during her university years
