the answer is A. here why. if we take the 45 times 5 you get the answer of how much she made all together for babysitting, if she only made 225 all together, you take 300-225=75. so the 75 represent the other she made by doing chores. you take 75 divide by 5 which is how many weeks it took it took you get 15 which how much she made each week by doing chores
