There is a bank 500 meters away from my home. I ran to the bank with my passbook and money, and saw that there was 4520 yuan in my passbook, and I was going to deposit it in 450 yuan today, so a * * * is 4520-450 = 4970 yuan. I stood on tiptoe, carefully handed my passbook and 450 yuan money to my assistant aunt, and told her, "I have 450 yuan money here. Please help me to deposit it in the bank for 3 years." The assistant aunt counted it with a smile and found that all the money was in the bank, and there was no difference at all. What a great responsibility!
When the money is saved. I came home with my passbook, and suddenly I remembered that my math teacher had taught us how to calculate interest and interest tax. So, I excitedly spread out a blank sheet of paper and began to calculate. The interest rate for three years is 3.24%, and interest = principal × interest rate × time, so my interest = 4970×3.24×3 = 483.084 (yuan). Wow, I can get many benefits! Then calculate the interest tax. Interest tax is 5%, 483.084× 5% = 24. 1542 (yuan) ≈24.2 (yuan). So three years later, I
A * * * has 4970-483.084-24.2 = 5428.884 yuan.
Ah, I gained a lot of knowledge in this deposit. I not only learned to save money by myself, but also learned to calculate the interest and interest tax in my life!
Today, when my father went to save money, he said to me, "Didn't you learn how to save money reasonably this semester?" This time you go to the bank with me and let me see how math is this year! " I agreed at once, because my math scores have improved this semester, not a small step, but a big step!
When I came to the bank, I saw a vertical poster, just below. Dad began to ask questions: "I have 1000 yuan here." How much can I get back in two years? " By the way, don't forget to pay taxes, because paying taxes is the obligation of every citizen. "Dad never forgets to educate his daughter." Dad, you haven't told me the interest rate yet. ""Little Tiger bug, didn't you see the poster at the door when you came in? " "Ha, I forgot." "Look at this memory, it's really bad, it's not as good as me!" "As far as you are concerned, I couldn't find my mobile phone last time, but I called you to find it." "Counting on you! "I immediately took out my paper and pen and calculated it." Dad, I calculated that the money you can get after two years is 1088.92 yuan. " "It seems that mathematics is doing well this semester. Let's ask my aunt, shall we? "
Before coming to the counter, my father reported the information to my aunt in the bank. My aunt told my father that I could really get back 1088.92 yuan after two years. My father said to me, "I have made great progress in my studies this semester." Hearing this, I praised Wang Po for selling melons: "Of course, who is your daughter!
