Q: Ella has 4 bags with 20 apples in each bag and six bags with 25 apples in each bag. If Ella sells 200 apples, how many apples does Ella has left?
A: 4 bags have 4 x 20 = 80 apples. And, six bags have 6 x 25 = 150 apples. Thus, Ella has 80 + 150 = 230 apples in all. Therefore, Ella has 230 - 200 = 30 apple left. The answer is 30.

Q: Carla works at a food bank and she currently has stocked up 2000 cans of food. One day, 500 people showed up and took 1 can of food each. Carla had to then restock 1500 more cans to keep up with demand. The next day, 1000 people showed up and took 2 cans of food each. Carla restocked again with 3000 cans of food this time. How many cans of food did Carla give away?
A: One day, 2000 - 500 = 1500 cans of food were left. It was then restocked to 1500 + 1500 = 3000 cans. 1000 * 2 = 2000 cans were taken the next day. 3000 - 2000 = 1000 cans were left. It was restocked once more to 1000 + 3000 = 4000 cans of food. Carla gave away 500 + 2000 = 2500 cans of food. The answer is 2500.

Q: Barbara asked the butcher for 4 1/2 pound steaks that cost $15.00/pound. She also asked for a pound and half of chicken breasts that were $8.00 a pound. How much did she spend at the butchers?
A:
She ordered 4 1 / 2 pound steaks so that's 4 * .5 = 2 pounds of steak. The steak cost $15.00 a pound and she bought 2 pounds so that's 15 * 2 = $30.00 for 4 steaks. She also needed 1.5 pounds of chicken breasts at $8.00 a pound so that's 1.5 * 8 = $12.00 for chicken. The steaks cost $30.00 and the chicken cost $12.00 for a total of 30 + 12 = $42.00 spent at the butchers. The answer is 42.
