Choosing not to complete this puzzle will not affect your grade in any way. Ben's Mom gives him an envelope of cash to bring to his Dad's store. She tells him how much she put in the envelope. On his way to his Dad's store, Ben sees a vinyl Abbey Road album at a yard sale for $0.50. Since Ben has no cash of his own, he dips into the envelope to buy the album. When he gets to his Dad's store, Ben opens the envelope only to find twice as much money left in the envelope as his Mom said she had placed there! Ben mentally adds the $0.50 he spent at the yard sale to the amount left and realizes that his Mom muddled up the dollars and cents when she told him how much the envelope held. The number of dollars she named was actually the number of cents; the number of cents she named was actually the number of dollars she put in. How much money did Ben's Mom actually put in the envelope?
