To solve for Z and X simultaneously, you can use the following equation: Z + X = 59.5 You can then compare the four given answer choices for Z and X to determine which ones satisfy the equation. For example, $1.51 + $22.35 = $23.86, which is not equal to 59.5, so neither of these answer choices is correct. However, $25.08 + $3.72 = $28.80 which is equal to 59.5, so the correct answer choices for Z and X are $25.08 and $3.72, respectively.
