Final answer:
Without the cost of the regular card, we cannot determine the exact price of the singing card. To find the answer, one would need to add $2.89 to the known cost of the advertised card.
Step-by-step explanation:
The question asked is about calculating the price of a singing card based on the cost of another card advertised, to which it costs $2.89 more. Unfortunately, the information provided does not specify the cost of the card in the advertisement, so we cannot determine the exact cost of the singing card. To solve this if we had the cost of the regular card, we would simply add $2.89 to that cost to get the price of the singing card.
For example, if the card in the ad costs $5.00, then we would calculate the cost of the singing card as follows: $5.00 (cost of the advertised card) + $2.89 (additional cost) = $7.89 (cost of the singing card).
