A) About $42
B) About $35
C) About $36
D) About $39

Answer 1

To estimate the total cost of 3 CDs priced at $12.89 each, round the price to $13 per CD and multiply by the quantity, resulting in an estimated cost of $39.

Step-by-step explanation:

If a student wants to buy 3 CDs for $12.89 each and needs to estimate the total cost, we start by rounding the cost of one CD to the nearest dollar, which is $13. Multiplying this estimated price by the quantity gives us an estimated total:

$13 × 3 CDs = $39

Therefore, the estimated total cost for the 3 CDs is about $39, which corresponds to option D.
