b) 4b - 3

Explanation:

Answer 2

a) b - 3

b) 4b - 3

Explanation:

Mandy scores b points in a basketball game:

• Mandy = b

Jay scores 3 points less than Mandy:

• Jay = b - 3

Kareem scores 2 times as many points as Mandy:

• Kareem = 2b

Therefore, the number of points Jay scores in terms of b is b - 3.

To find the total number of points the three players score in terms of b, sum the three expressions:

⇒ b + (b - 3) + 2b

⇒ b + b - 3 + 2b

⇒ 2b - 3 + 2b

⇒ 4b - 3

Therefore the total number of points the three players score in terms of b is 4b - 3.
