Answer:

Step-by-step explanation:
The dentist orders 15 boxes of floss and 20 boxes of toothbrushes each month.
The floss is sold 70 to a box, this means about 70 numbers of floss occupies each box of floss. To get the total number of floss items in the 15 boxes of floss, we have to multiply the number of boxes of floss by the number of floss present in each box. Mathematically,
70 × 15 = 1050 items of floss
The boxes of toothbrushes is 20 . For each box the number of toothbrushes is 50 . To get the total number of tooth brushes we multiply the number of boxes by the total number of toothbrushes in each box.
50 × 20 = 1000 items of toothbrushes.
The dentist orders 1050 number of floss and 1000 number of toothbrushes. The items are 2 different items namely floss and toothbrushes.
