On Tuesday, Sally delivered 20% more items than on Monday.
On Wednesday, Sally delivered 50% less items than on Tuesday.
On Wednesday, Sally delivered a total of 72 items.
Calculate the number of items that Sally delivered on Monday.
Answer:
Wednesday = 50% x Tuesday
Therefore, no of items on Tuesday = 72/ 0.5 = 144 items
Tuesday 1= Monday x 1.20
Therefore, no of items on Monday = 144/1.2 = 120 items
