Samuel bought 4 rolls of tape to seal boxes. Each roll contains 32.9 meters of tape. He uses 1 1/5 meters of this tape to seal e

Anestetic [448]

Answer:

109.33 boxes

Step-by-step explanation:

The first step is to calculate the total number of tape

= 32.9 × 4

= 131.6 m

Therefore the total number of boxes that Samuel will use to seal the boxes can be calculated as follows

= 131.6/ 1 1/5

= 131.6 ÷ 6/5

= 131.6 × 5/6

= 658/6

= 109.33 boxes
