[Question]: 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?
[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.
So the answer is 42.

[Question]: John buys 2 packs of gum and 3 candy bars. Each stick of gum cost half as much as the candy bar. If the candy bar cost $1.5 each, how much did he pay in total?
[Answer]: The gum cost $1.5 / 2 = $.75 per pack. So he pays $.75 * 2 = $1.5 for the gum. He pays $1.5 * 3 = $4.5 for the candy bars. So in total, he pays $1.5 + $4.5 = $6.
So the answer is 6.

[Question]: Dorothy sells glass frames at half the price that Jemma sells them. Jemma sells the glass frames at 5 dollars each, selling twice as many frames as Dorothy does. If Jemma sold 400 frames, how much did they make together in total from the sale of the glass frames?
[Answer]:
If Jemma sold 400 glasses frames at $5 each, she made 400 * $5 = $2000. Jemma sold twice as many frames as Dorothy, meaning Dorothy sold 400 / 2 = 200 frames. If Dorothy sold her glasses frames at half the price that Jemma sold hers, then it means she sold her glasses frames at $5 / 2 = $2.5 per glasses frame. In total, Dorothy made $2.5 * 200 = $500 from the sale of her glasses frames. Together, they made $2000 + $500 = $2500 from the sale of the glasses frames.
So the answer is 2500.
