📝 Answered - The buffet restaurant charges $3.25 for the first pound of chicken salad and $2.85 for each pound thereafter. If \( y \) represents the total cost and \( x \) represents the total number of pounds, what is the function rule for this pattern? A. \( y = 3.25 - 2.85(x - 1) \) B. \( y = 3.25 - 2.85(x + 1) \) C. \( y = 3.25 + 2.85(x + 1) \) D. \( y = 3.25 + 2.85(x - 1) \)

📝 Answered - Marcie wants to enclose her yard with a fence. Her yard is in the shape of a triangle attached to a rectangle. The area of this figure can be found by the formula: \[ A = (wh) + 0.5(bh) \] If Marcie wants the total area to be larger than a specified value, she can use the formula: \[ A > (wh) + 0.5(bh) \] Rewrite this formula to solve for \( b \). Show all steps in your work.

📝 Answered - The sum of two consecutive odd integers is 284. Write an equation and solve to find the two integers. --- Equation: Let the first odd integer be \( x \). Then the next consecutive odd integer is \( x + 2 \). \[ x + (x + 2) = 284 \] Solve for \( x \): \[ 2x + 2 = 284 \] \[ 2x = 282 \] \[ x = 141 \] So, the two consecutive odd integers are \( 141 \) and \( 143 \).
