Devon is buying 3 greeting cards that cost $0.97 each. How can rounding be used to estimate the total cost of the cards?

Since each card is about $1, the total cost is approximately 3 + 1 = $4.
Since each card is about $1, the total cost is approximately 3 × 1 = $3.
Since he is buying about 10 cards, the total cost is approximately 10 × 0.97 = $9.70.
Since he is buying about 10 cards, the total cost is approximately 10 + 0.97 = $10.97.

Answer:

Since each card is about $1, the total cost is approximately 3 × 1 = $3.

Step-by-step explanation:

So 3 x 1 = 3

1 > 0.97

0.97 x 3 ≈ 2.91 which if rounded to the nearest WHOLE number it would be approximately 3$
