Answer:
$9.98 is how much more money is needed to make the purchases.
Explanation:
First, you would add the cost of the shirt ($29.99) and the cost of the shoes ($79.99),
$29.99 + $79.99 = $109.98
then...... subtract the budget ($100.00) from the total cost of the shirt and shoes ($109.98),
$109.98 - $100.00 = $9.98
$9.98 is the amount of money still needed to make the purchases.
