Food (55÷100)×3 000 = R1 6502. Food (14÷100)×20 000 = R2 800∴ 2 spent more 52.2.1 R1 630÷4 = R407,50= R400 to nearest R100 22.2.2 ( 9 ×4,98) + ( 7×4.70) + (2×3,98) = R85,68 42.2.3 A. 2×R5,90 = R11,80 per kgB.R12,99÷2,5 = R5,20 per kgC. R27÷5 = R5,40 per kgD R50 ÷10 = R5 per kg ∴D B C A 52.2.4 It will use up too much of her budget on oneitem.(or similar answer) 23.1.1 2600÷2÷5 = 260 people 33.1.2 350×260 = 91 000ml = 91liters 23.1.3 260÷(12×2) = 10,8 ∴ 11 crates 33.1.4 910÷26000×100 2= 0,38%3.2.1 30 games 13.2.2 + Goal Diff means more goals scored forthan against- Goal Diff means more goals scored againstthan for. 23.2.3 A. 30 – (12+4) = 14B. (39 – 33) = +6C. 32 – C = 4 ⇒ C = 28D. (D–42) = –2 ⇒ D = 40 43.2.4 Free State Stars drew most of the games thatthey did not lose. Mamelodi Sundowns won most of the gamesthey did not lose. Wins score 3 points whereas draws onlyscore one point.Or any other valid solution. 23.2.5 From the table we see that a win is worth 3point and a draw 1 point. So the finalpoints for Thembisa Classic will be(7×3) + (9×1) = 30 points 34.1 Caledonian Kwikspar 14.2 17:56:00 = 5:56pm 24.3 R143,60 24.4 R143,60 +R31,84 = R175,44(R24,56÷R175,44)×100 = 13,999≈ 14% 34.5 R143,60÷470,88unit = R0,30496 per unit= 30,50 cents per unit 34.6 470,88 ÷ 35 = 13,45 days approx. 13 days 34.7 August has 31 days31×35 = 1085 units1085×30,50 cents = 33092,5 cents≈ R331R331 + R31,84 = R362,84VAT = 14% of R362,84= R50,80Final total = R413,64ORIf the learner used 30 days:30×35 = 1050 units1050×30,50 cents = 32025cents ≈ R320R320 +R31,84 = R351,84VAT = 14% of R351,84= R49,26Final total = R401,10 6Copyright reserved
