5 pounds of taffy for Isabel and 1 pound of taffy for Ramona.

Step-by-step explanation:

In an eight-hour day, Isabel can produce 15 pounds of taffy or 3 pounds of chocolate chip cookies.

x = 5

In an eight-hour day, Ramona can produce 6 pounds of taffy or 6 pounds of chocolate chip cookies.

x = 1

Hence, the opportunity cost of producing 1 pound of chocolate chip cookies is: 5 pounds of taffy for Isabel and 1 pound of taffy for Ramona.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
