Answer:

  • 43 minutes
  • $47

<u>1. Cell phone usage</u>

Mon to Sun = 38, 62, 40, 10, 30, 55, 65

  • Mean = (38+62+40+10+30+ 55 + 65)/7 = 43 minutes rounded

Jan to Dec = $40 $42 $40 $38 $48 $50 $58 $62  $56 $46  $44 $44

Sarah's surfboards charges a fee of $60 to rent a surfboard and then $10.50 per hour. Sally's surfboards does not charge a fee,
Zanzabum

Answer:

12 hours

Step-by-step explanation:

Let the number of hours be represented as h.

Sarah's surfboards charges a fee of $60 to rent a surfboard and then $10.50 per hour.

Mathematically ,

60 + 10.50h

Sally's surfboards does not charge a fee, but they cost $15.50 per hour

Mathematically,

15.50h

Equating both equations together

60 + 10.50h = 15.50 h

Collect like terms

60 = 15.50h - 10.50h

60 = 5h

h = 60/5

h = 12 hours

Therefore, the number of hours that the cost will be the same to rent a surfboard for each shop is 12 hours.
