Homework Help: Math

Posted by Rich on Wednesday, September 3, 2008 at 7:27pm.

Can you help me with my son's homework question:
Maria earned $110, which is $86 more than twice the amount Joan earned. How much did Joan earn?
a. $12
b. $18
c. $24
d. $30

I would like to know the 5th grade equation that represents the answer. I guess I'm not smarter than a 5th grader on this one. Thanks for your help.

well, TwiceJoaneared + 86 is 110
so twiceJoanearned must be 24 so joan earned....

Seems Like Joan earned $12.
Thanks!
