The table shows the number of hot dogs Frank’s hot dog stand sold this weekend.
A. Estimate the number of hot dogs sold by rounding each number in the table to the nearest thousand and finding the sum.
B. Write and solve an equation to find how many hot dogs were sold.
A. 4,000 + 1,000 + 4,000 = 9,000
B. 3,825 + 1,297 + 4,175 = h
h = 9,297

Cindi says, "When rounding to the nearest thousand, 286,734 rounds to 290,000." Do you agree? Explain.
○ Yes. 286,734 rounded to the nearest thousand is 290,000 because it is less than one thousand away.
○ No. 286,734 rounded to the nearest thousand is 286,700.
○ Yes. 286,734 rounded to the nearest thousand is 290,000 because there is a 0 in the thousands place.
○ No. 286,734 rounded to the nearest thousand is 287,000.
No. 286,734 rounded to the nearest thousand is 287,000.
