Don't know
To answer these questions and find out how much change Aidan and Sylvia should get back, we need to subtract the cost of the item from the amount of money they have. Let's calculate it step by step:
1/ Aidan has $5.00, and the cost of the tennis balls is $3.79.
To find out how much change he should get back, we subtract $3.79 from $5.00:
$5.00 - $3.79 = $1.21
So, Aidan should get $1.21 as change.
2/ Sylvia has $10.00, and the cost of the hairbrush is $6.88.
To find out how much change she should get back, we subtract $6.88 from $10.00:
$10.00 - $6.88 = $3.12
So, Sylvia should get $3.12 as change.
