Lyndsey has $50 to buy a jacket and a hat in the store. A jacket costs $39.08 and a hat costs$12.55. Lyndsey says she stays within the budget. Is she correct? Explain.

• Lyndsey is correct. $39.08 rounds to $30 and $12.55 rounds to $20, and $30 + $20 = $50.

• Lyndsey is correct. $39.08 + $12.55 = $51.63, which is less than $50.

• Lyndsey is correct. $39.08 rounds to $40 and $12.55 rounds to $10, and $10 + $40 = $50.

• Lyndsey is incorrect. $39.08 + $12.55 = $51.63, which is greater than $50.

Estimate 25.65 + 13.23 + 6.35 by rounding each number to the nearest tenth.

• 26 + 13 + 6 = 45

• 25.7 + 13.3 + 6.4 = 45.4

• 25.7 + 13.2 + 6.4 = 45.3

• 25.6 + 13.2 + 6.3 = 45.1
