Let's analyze each situation individually.
-
Jose has 4 packs of gum and 10 pieces of gum in each pack:
This is a simple multiplication problem, so we need to multiply the number of packs by the number of pieces per pack:
\( 4 \times 10 = 40 \)- Option a. 4x10=40 is the correct answer for situation 1.
-
Jose owes each of 4 friends $10:
To find the total amount he owes, we again multiply:
\( 4 \times (-10) = -40 \) (since owing money is a negative value)- Option c. 4x(-10)=-40 is the correct answer for situation 2.
-
Jose spent $4 for each of 10 baseball cards for his collection:
Here we multiply the price of each card by the total number of cards:
\( 10 \times 4 = 40 \)
We can express it as:
\( -4 \times (-10) = 40 \) (spending is negative, but the total expense is a positive outcome)- Option b. -4x(-10)=40 is the correct answer for situation 3.
-
Jose drank 4 ounces of juice on each of the previous 10 days:
This also involves multiplication. Total juice consumed:
\( 10 \times 4 = 40 \) can also be expressed involving negative values:
Since he is consuming juice, let's represent it negatively for total intake, but here it ends up being the spending count:
\( -4 \times 10 = -40 \) (negative because it's total spent but actual it isn't)- Option d. -4x10=-40 is the correct answer for situation 4.
Putting it all together:
- a. 4x10=40
- c. 4x(-10)=-40
- b. -4x(-10)=40
- d. -4x10=-40
