Emily gave 7 of her quarters to Eli. They now have the same amount of money. How much money did Eli start with?
Emily gave 7 of her quarters to Eli. They now have the same amount of money. How much money did Eli start with?
If Emily had Q quarters,and
Eli had R quarters, then we have
Q - 7=2R- There are MANY solution to this equation. But the ONLY one that meets the conditions stated is:
Q=21 and R=7, because,
Emily started with 21 quarters and Eli with 7 quarters, but,
21-7=14 quarters that Emily has after giving 7 to Eli, and
7+7 =14 quartes that Eli has now. So Eli started with:
7 X .25=$1.75, but after he got 7 more quarters from Emily, he now has:
14 X .25=$3.5 The amount of money that each has now.
