10. A farmer harvests 487 apples from one tree and 512 apples from another. b) If he wants to pack them into boxes that hold 21 apples each, estimate how many boxes he will need. Step 1: Use the estimated total number of apples from part a), which was 1,000 apples. Step 2: Round the number of apples per box. 21 apples rounded to the nearest ten is 20 apples. Step 3: Divide the estimated total apples by the estimated apples per box. 1,000 apples20 apples/box = 50 boxes 11. Sarah went grocery shopping. She bought: 2 cartons of milk at K8.95 each. 1 loaf of bread at K4.10. A tray of eggs at K15.80. Estimate the total cost of her shopping by rounding each item to the nearest Kina. Show your working. Step 1: Estimate the cost of milk. Round K8.95 to the nearest Kina: K9.00. Cost for 2 cartons of milk: 2 × K9.00 = K18.00. Step 2: Estimate the cost of bread. Round K4.10 to the nearest Kina: K4.00. Cost for 1 loaf of bread: 1 × K4.00 = K4.00. Step 3: Estimate the cost of eggs. Round K15.80 to the nearest Kina: K16.00. Cost for 1 tray of eggs: 1 × K16.00 = K16.00. Step 4: Calculate the total estimated cost. K18.00 + K4.00 + K16.00 = K38.00
