Let's evaluate each of Jose's situations step by step:
-
For the number of pieces of gum:
- Jose has 4 packs of gum, with each pack containing 10 pieces of gum.
- Therefore, the total pieces of gum = 4 packs × 10 pieces/pack = 40 pieces.
- Thus, Jose has 40 pieces of gum.
- The correct mathematical equation is a. 4x10=40.
-
For the total amount Jose owes his friends:
- He owes each of his 4 friends $10.
- Therefore, the total amount owed = 4 friends × $10/friend = $40.
- Thus, Jose owes a total of $40.00.
-
For the total amount he spent on baseball cards:
- Jose spent $4 on each of 10 baseball cards.
- Therefore, the total spent = 10 cards × $4/card = $40.
- Thus, Jose spent a total of $40.00.
-
For the amount of juice he drank over the past 10 days:
- Jose drank 4 ounces of juice each day for 10 days.
- Therefore, the total ounces of juice drank = 4 ounces/day × 10 days = 40 ounces.
- Thus, Jose had 40 more ounces of juice ten days ago.
In summary:
- Jose has 40 pieces of gum.
- Jose owes a total of $40.00.
- Jose spent a total of $40.00.
- Jose had 40 more ounces of juice ten days ago.
