Multiply or Add Puzzle - Solution
The Puzzle:
Guy goes into a store and buys 4 things. The cashier tells him his bill
comes to $7.11.
"Wait a minute," the guy says. "I saw you multiply the prices instead of
adding them."
"Doesn't matter," the cashier responds. "The sum is also $7.11."
What were the 4 prices?
Our Solution:
$3.16 + $1.50 + $1.25 + $1.20 = $7.11
$3.16 × $1.50 × $1.25 × $1.20 = $7.11
