Sarah and Bryan went shopping and spent a total of $47.50 Bry an spent $15.50 less than what Sarah spent how much did bryan spen

Bogdan [553]

Since Bryan spent $15.50 less than Sarah, you would start by dividing the total amount they spent together in half.

$47.50 ÷ 2 = $23.75

Then you would take Bryan's 1/2 of the total and subtract $15.50.

$23.75 - $15.50 = $8.25

So, it looks like Bryan spent $8.25.

Check step:

If you add it all back together:

Sarah + Sarah Bryan = Total
$23.75 + $15.50 + $8.25 = $47.50
