Answer:
Each stuydent must raise $15.61 to reach their goal.
Step-by-step explanation:
Their goal is 483.62, but they already have 218.25 so we subtract,
483.62 - 218.25 = 265.37
Since there are 17 students and they raise the same amount we need to divide by the amount of students to find out how much money each of them need to raise to add up to their goal.
265.37/17 = $15.61
Step-by-step explanation:
They are equal because when we flip or reflect ABC onto DCB we are going to have the same size and the same shape
