Answer:
To calculate the amount of money left on Andy's gift card, we need to subtract the amount he spent from the initial value of the card.
Andy spent 2/5 of his gift card on a new shirt. To find this amount, we multiply the value of the gift card by 2/5:
2/5 * $100 = $40
Therefore, Andy spent $40 on the new shirt.
Next, Andy used his gift card to buy a pair of sunglasses worth $10.
To find the remaining balance on the gift card, we subtract the total amount Andy spent from the initial value of the card:
$100 - ($40 + $10) = $100 - $50 = $50
After purchasing a new shirt for $40 and a pair of sunglasses for $10, there is $50 remaining on Andy's gift card.
