Answer sheet

1. 180 — 30 × 5 = 150 and 6 × 5 = 30. 150 + 30 = 180.
2. 60 × 3 + 4 × 3 — 64 = 60 + 4, and both parts must be multiplied by 3: 60 × 3 + 4 × 3 = 180 + 12 = 192.
3. 300 — 25 × 10 = 250 and 25 × 2 = 50. 250 + 50 = 300.
4. About 1000 — Round to 50 × 20 = 1000. The exact answer is 1029.
5. 232 — 50 × 4 = 200 and 8 × 4 = 32. 200 + 32 = 232.
6. 480 — 32 × 10 = 320 and 32 × 5 = 160. 320 + 160 = 480.
7. $102 — 17 × 6: 10 × 6 = 60 and 7 × 6 = 42. 60 + 42 = 102, so the tickets cost $102.
8. 624 — 48 × 10 = 480 and 48 × 3 = 144. 480 + 144 = 624.
