Claire wants to buy a guitar that costs $300. She saves $45 each week from her babysitting job. She also saves the same amount each week from her allowance of doing chores. If Claire has enough money to purchase the guitar after 5 weeks, how much did she save each week from her allowance of doing chores? A. $15 B. $30 C. $45 D. $60

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
