Answer:

  • A = 0.85(b +47)
  • $143.65

Step-by-step explanation:

Since the number of bagels sold already is 47, the total number of bagels sold will be b+47. The revenue from each sale is $0.85, so the total revenue will be ...

  A = 0.85·(b +47)

This equation can be written in different forms, but this satisfies the requirement for "an equation."

__

Since b is the number of addition bagels, when 122 additional bagels are sold, the value of b is 122. Then the equation becomes ...

  A = 0.85·(122 +47)

  A = 0.85·169 = 143.65

Revenue will be $143.65 when 122 additional bagels are sold.

(13p5 + 6p - 12p2) - (-9p - p2 - 13p5)
anastassius [24]

Answer:

Step-by-step explanation:

13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵

{Distribute  (-1) to the second expression}

= <u>13p⁵ + 13p⁵</u>    <u>-12p² + p²</u>     <u>+ 6p + 9p</u>

{Combine like terms}

= 26p⁵ - 11p² + 15p
