Answer:

No, his estimation is not accurate.

Step-by-step explanation:

Given,

He plans to purchase five items that cost $5.79, $7.63, $3.46, $2.99, and $3.65.

Since, 5.79 ≈ 6, 7.63 ≈ 8, 3.46 ≈ 3, 2.99 ≈ 3, 3.65 ≈ 4,

Thus, total amount of his purchasing = 5.79 + 7.63 + 3.46 + 2.99 + 3.65 ≈ 6 + 8 + 3 + 3 + 4 = 24

But, 24 > 20,

Hence, his money is not enough for his purchases,

⇒ He did not estimate accurately because he did not round the prices correctly.

<span>Larry did not round correctly. He used front-end estimation, but he did not round up when appropriate. His estimate will be lower than the amount of money he needs.</span>
