Olivia purchases gifts for her mom and grandma for Mother's Day. The first is a pair of sunglasses for $16.35 and the second is a bracelet. Her total is $39.75. How much did she spend on the bracelet?
All you have to do is subtract the total ($39.75) and the the first gift ($16.35).
$39.75 - $16.35 = $23.4
We can check our answer by adding $16.35 and $23.4
$16.35 + $23.4 = $39.75
If you write down what you already know it makes things much simpler:)
