Question

Kai saved $98 dollars from his summer jobs. Then he spent $31 to go to a basketball day camp. After camp, he made $22 more mowing lawns. How much does Kai have saved now? Kai calculates that he now has $45 in savings. Which answer correctly explains whether Kai’s answer is reasonable? Kai’s answer is not reasonable. He had about $100 in savings and then spent about $30, so subtract $100 – $30 to find that he has about $70 left. He made about $20 more, so $70 + $20 is about $90 in savings. Kai’s answer is reasonable. He had about $100 in savings. He had about $30 for camp and about $20 from mowing lawns, so $30 + $20 = $50. Subtract $100 – $50 to find that he has $50 in savings. Kai’s answer is not reasonable. He had about $90 in savings and then spent about $20, so $90 – $20 is about $70. He spent about $30 on camp, so $70 – $30 is about $40 in savings.
