85,208 - ________ = 78,172
85,208 - 78,172 = 7,036
85,208 - 7,036 = 78,172
899 + 798 + 697 + 596 = ________
899 + 798 + 697 + 596 = 2,990
80,500 - 79,000 + 96,000 -20,000 = ________
80,500 - 79,000 = 1,500
96,000 - 20,000 = 76,000
1,500 + 76,000 = 77,500
Mrs. Davidson bought a car for $18,000. She also bought new tires that cost $16,500 less than the car. How much did she pay for the car and the new tires altogether?
Car = $ 18,000
Tires = $18,000 - 16,500 = 1,500
Car ($18,000) + Tires ($1,500) = $19,500
Round 18,805 to the nearest thousand.
19,000
3,821 - 2,999 = ________
3,821- 2,999 = 822
31,670 + 988 = _________
31,670 + 988 = 32,668
1,000,000 - 856,000 + 30,000 - 15,000 = _________
1,000,000 - 856,000 = 144,000
30,000 - 15,000 = 15,000
144,000 + 15,000 = 159,000
There were 10,000 people at Zilker park on Friday. 3,000 of them were men. There were 1,000 more women than men at the park and the rest were children. How many children were at the park?
10,000 total people at the park
men = 3,000
women = men + 1,000 = (3,000 + 1,000) = 4,000
Men + Women= (3,000 + 4,000) = 7,000
Children= total number of people at the park - men and women = (10,000 - 7,000) = 3,000 children.
Estimate for 71,078 + 18,805
71,000 + 19,000 = 90,000
20,000 - 672 = _______
20,000 - 672 = 19,328
31,670 = 18,790 + _______
31,670 - 18,790 = 12,880
31,670 = 18,790 + 12,880
98,000 - 60,000 + 50,000 - 25,000 = __________
98,000 - 60,000 = 38,000
50,000 - 25,000 = 25,000
38,000 + 25,000 = 63,000
8,152 people were at the Circuit of the Americas on Friday. 1,250 more were at the Circuit of Americas on Saturday than on Friday. 899 fewer people were at the Circuit of the Americas on Sunday than on Saturday. How many people attended the Circuit of Americas altogether on Saturday and Sunday?
Friday= 8,152
Saturday= Friday + 1,250 = (8,152 +1,250) = 9,402
Sunday = Saturday - 899 = (9,402 -899) = 8,503
Saturday + Sunday = 9,402 + 8,503 = 17,905
Estimate 38,753 + 51,335
39,000 + 51,000 = 90,000
80,000 - _________ - 20,000 = 40,000
80,000 - 20,000 = 60,000
60,000 - 40,000 = 20,000
80,000 - 20,000 - 20,000 = 40,000
10,000 = 2,000 + ________
10,000 - 2,000 = 8,000
10,000 = 2,000 + 8,000
A farmer sold 4,216 chicken eggs and 695 duck eggs last year. He then sold 6,234 chicken eggs and 876 duck eggs this year. How many more eggs did he sell this year than last year?
4,216 + 695 = 4,911
6,234 + 876 = 7,110
7,110 - 4,911 = 2,199
Dillards had 2,856 shirts in the warehouse. There were 2,002 fewer shirts at the store than in the warehouse. Some shirts transferred from the warehouse to the store and now the store has 1,449 shirts. How many shirts were transferred from the warehouse to the store?
Warehouse = 2,856 shirts
Store = Warehouse- 2,002 shirts = (2,856 - 2,002) = 854
Store = 1,449 shirts ( 1,449 -854 = 595 shirts from the warehouse transferred)
Warehouse = 2,856 - 595 = 2,261 shirts now in the warehouse
Estimate 320,176 - 28,524
320,000 - 29,000 = 291,000
70,000 - 18,500 - 4,600 = _______
70,000 - 18,500 - 4,600 = 46,900
40,000 + __________ + 30,000 = 100,000
40,000 + 30,000 = 70,000
100,000 - 70,000 = 30,000
40,000 + 30,000 + 30,000 = 100,000
