in their wallets. Henry has $9
less than Carmen. Manuel has 2
times what Carmen has. How much does each have?
Answer provided by our tutors
Let
x = the money Carmen has
x - 9 = the money Hanry has (Henry has $9 less than Carmen)
2x = the money Manuel has (Manuel has 2 times what Carmen has)
Carmen, Henry, and Manuel have a total of $67 in their wallets:
x + (x - 9) + 2x = 67
........
........
x = $19
Carmen has $19.
Henry has 19 - 9 = $10.
Manuel has 2*19 = $38.
