Question 1009588
The problem says:"Jill has 6*Joan, and it says that together, this is 6*Joan+Joan= 84. So let's call the dimes x:
6x+x= 84 Add x on left:
7x= 84 Now divide both sides by 7:
x= 12 Joan has 12 dimes, and Jill has:
12*6= 72
------------------------------
Check:
Joan has 12 and Jill has 72:
12+72= 84, we have the correct answer.
