Booklet 1A - Section 1

• 2a). CPP contribution calculation: The contributions are 3.2% of gross income between $3500.01 and $36 900 (see "MATHPOWER 11" , page 533). For a gross income:
  • less than $3500, the CPP contribution: (there will be no CPP contribution)
  • between $3500.01 and $36 900, the CPP contribution: (gross income - $3500)
  • over $36 900, the CPP contribution: ($36 900 - $3500)
• 2b). Be careful when you calculate Federal Tax: Use Federal Tax table ("MATHPOWER 11" , page 534)
  • study the Federal Tax calclulation ("MATHPOWER 11" , page 535)
• 2c) annual Income = gross income - deductions
  • deductions: (CPP + EI + income tax + RRSP)
    • deductions that are not included in this question: union (professional) dues, Registered Pension Plan (RPP), child-care expenses, and moving expenses
• 3. The fomula to calculate compound interest is A = P(1 + i)ⁿ. Remember

  i =                     rate%                     , n = number of compounding periods /year * #years
            #compounding periods/year

  See Solution: "Pure Mathematics 20 Module 1", page 20, and Solution 1 ("MATHPOWER 11" , page 542)
