« CENGAGE MINDTAP Chapter 13 Homework Scenario 1: Individual Retirement Accounts (IRAs) allow workers to shelter a portion of their income from taxation. Suppose the maximum annual contribution to accounts of this type is $6,000 per person. Now suppose there is an increase in the maximum contribution, from $6,000 to $9,000 per year. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of saving causes the equilibrium interest rate in the market for loanable funds to and the level of investment spending to Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital within some relevant time period. Suppose the government implements a new investment tax credit. Shift the appropriate curve on the graph to reflect this change. cess Tips The implementation of the new tax credit causes the interest rate to and the level of investment to . cess Tips Scenario 3: Initially, the government's budget is balanced; then the government responds to the conclusion of a war by significantly reducing defense spending without changing taxes.

He sold an old equipment TK460000; its cost being TK390000 and accumulated depreciation TK90000. Swapan earned a dividend from a UK company listed with the London Stock Exchange, £6000 after withholding tax @10%. During this year, Mr. Sen got married and spent TK 185000 for a honeymoon in Sundarban. He invested TK 20000 in defense savings certificates, TK50000 in company shares and securities, and he bought a life insurance policy for TK2500000 with an annual premium being TK30000. He also donated TK300000 to Dhaka Medical College Hospital and gifted a car TK 800000 to his friend's daughter's marriage. Requirement 1: Swapan Sen's income tax return. BPS1-TK120. (Based on the Income Tax Law Act 2023 of Bangladesh Point of view). Requirement 2: What is a surcharge? What is its purpose? How is it determined? How is it different from wealth tax? (Based on the Income Tax Law Act 2023 of Bangladesh Point of view).

Design a single-ended primary inductance converter (SEPIC) for charging batteries at 27.5 V from a solar panel that produce a range of voltage from 16V to 34V. Assuming the batteries having a constant resistance $R_B$ of 60?. Design the SEPIC with continuous current and switching frequency of 1400Hz. The allowable output voltage ripple is 4%. a) Show all the design steps and circuit diagram to obtain the inductor value for $L_1$, $L_2$, $C_1$, and $C_2$. (12 marks) b) Convert your solution into an Excel worksheet. (4 marks) c) At time (1-D)T to T, energy generated form the solar panel is not harvested by the SEPIC.
