Unity makes $56 a week +50% off the cost of news that she serves use the equation y equals 0.1 5x +56 to predict what she makes in a week when she serves $435 worth of meals

We are already given with the equation to determine the amount Unity makes in a week. That is,
                             Y = 0.15x + 56
Substituing $435 to x,
                                Y = 0.15($435) + 56
                                   = $121.25
Therefore, Unity makes $121.25 in a week when she served $435 worth of meals.
