Final answer:
The question involves estimating the total cost of buying 3 singles at $0.99 each and 2 albums at $9.55 each. The estimated total cost of buying 3 singles and 2 albums is $22.07.
Step-by-step explanation:
To estimate the total cost of buying 3 singles and 2 albums, we need to multiply the cost of each item by the quantity and then add these costs together. Each single costs $0.99, so 3 singles would cost 3 x $0.99 = $2.97. Each album costs $9.55, so 2 albums would cost 2 x $9.55 = $19.10.
To find the total cost, we add the cost of the singles and the albums: $2.97 + $19.10 = $22.07.
Therefore, the estimated total cost of buying 3 singles and 2 albums is $22.07.
