"Education Savings" Univariate Quadratic Equation PPT Courseware 2

Terms used in savings problems: principal, interest, sum of principal and interest, number of periods, interest rate;

Calculation formula:

Sum of principal and interest = principal + interest,

Interest = principal × interest rate × number of periods,

The time of deposit is called the period,

The ratio of interest to principal in each period is called the interest rate.

my country has levied personal income tax on savings deposit interest since November 1, 1999, that is, 20% of the interest generated by deposits. However, interest tax is not levied on education savings and the purchase of treasury bills for the time being.

In order to prepare for Xiaoying's college tuition of 5,000 yuan in 6 years, Xiaoying's parents are now participating in education savings. Can you help them design a savings method?

4. Deposit for a three-year period first, and deposit the principal and interest year by year for three consecutive years.

Which of the above options requires the least initial deposit?

Homework:

1. In order to prepare for his 16,000 yuan tuition fee when he goes to college, Xiao Ming's parents participated in education savings when he was in the first year of junior high school. They planned to save part first and then borrow part when he went to college. Xiao Ming's parents are saving for 6 years (annual interest rate is 2.88%), and plan to pay off the college loan in 8 years (annual loan interest rate is 6.21%), of which 50% of the loan interest is subsidized by the government. If the interest earned from participating in education savings is equal to the interest spent on applying for a loan, how much money did Xiao Ming’s parents spend to participate in education savings, and how much are they prepared to borrow? (Results are retained as integers)
