Question

Nancy is saving $2 from her allowance every week. Marco is saving $1 the first week, $2 the second week, $3 the third week, and so on. At the end of 10 weeks who would have saved more? How much more?

Answer 1

Marco saves $35 more than Nancy.

Explanation:

Nancy saves $2 per week. After 10 weeks she will have saved 2 * 10 = $20.

Marco saves $1 the first week, $2 the second week, and $3 the third week and so on. This means for 10 weeks he will save 1+2+3+4+5+6+7+8+9+10=$55.

Marco saves $35 more than Nancy.
