Nancy is saving $2from 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 money?

If we assume that Nancy continues saving $2 from her allowance every 2 weeks, we know that it can be represented as:

2x10=20

This means at the end of 10 weeks, Nancy will have $20.

However, for Marco, as the weeks go up, He saved one more dollar. This can be represented as:

1+2+3+4+5+6+7+8+9+10=55

This means that at the end of 10 weeks, Marco will have $55.

At the end of 10 weeks, Marco will have saved more money than Nancy. 

Nancy would have $20 because $2x10=$20
Marco would have $55 add up 10+9+8+7+6+5+4+3+2+1=$55

so at the end of ten weeks Marco has the most. 

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
