Reasoning and answer: 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: 42

Reasoning and answer: 5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00.
The answer: 23
