PART ONE Mathematics Fundamentals and Business Applications

Chapter 1 Review of Arithmetic

Exercise 1.1

A. 1. 12 + 6 ÷ 3 = 12 + 2 = 14

2. (3 × 8 − 6) ÷ 2 = (24 − 6) ÷ 2 = 18 ÷ 2 = 9

3. (7 + 4) × 5 − 2 = 11× 5 − 2 = 55 − 2 = 53

4. 5 × 3 + 2 × 4 = 15 + 8 = 23

5. 6(7 − 2) − 3(5 − 3) = 6(5) − 3(2) = 30 − 6 = 24
20 − 16 4 1
6. = = = 0.2
15 + 5 20 5
7. 4(8 − 5) 2 − 5(3 + 22 ) =4(3) 2 − 5(3 + 4) =4(9) − 5(7) =36 − 35 = 1

8. (3 × 4 − 2) 2 + (2 − 2 × 7 2 )= (12 − 2) 2 + (2 − 2 × 49)

= 102 + (2 − 98) = 100 − 96 = 4
10
9. 250(1 + 0.08)
= 250(2.158925)
= 539.73

10. (1 + 0.04)
= − 1 1.169859
= −1 0.17

11. 30 × 600 − 2500 − 12 × 600= 18, 000 − 2500 − 7200= 8300

12. 1 − [(1 − 0.40)(1 − 0.25)(1 − 0.05)] =1 − [(0.6)(0.75)(0.95)] =1 − [0.4275] =0.5725 =0.57
13. 15 − 7 + 6(2 + 3) / 3
= 15 − 7 + 6(5) ÷ 3
= 15 − 7 + 30 ÷ 3
= 15 − 7 + 10
= 18
14. × 4 + 6(4 + 2)
= 8 × 4 + 6(6)
= 32 + 36
= 68

15. (1 − 0.7) − 4 × 20 ÷ 5
= (0.3) − 4 × 4
= (0.3) − 16
= −15.7
16. 50[(1 − 0.2)(1 − 0.175)(1 − 0.04)]
= 50[(0.8)(0.825)(0.96)]
= 50[(0.6336)]
= 31.68
17. 7a − 6[4 − (3a + 6)]
= 7a − 6[4 − 3a − 6]
= 7a − 6[−2 − 3a]
= 7a + 12 + 18a
= 25a + 12
18. 6a + 4b + 2(16 − 2a + b)
= 6a + 4b + 32 − 4a + 2b
= 2a + 6b + 32
