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?
She ordered 4 1/2 pound steaks so that's 4*.5 = <T>multiply(4, 0.5)=2.0 pounds of steak.
The steak cost $15.00 a pound and she bought 2 pounds so that's 15*2 = $<T>multiply(15, 2)=30 for 4 steaks.
She also needed 1.5 pounds of chicken breasts at $8.00 a pound so that's 1.5*8 = $<T>multiply(1.5, 8)=12.0 for chicken.
The steaks cost $30.00 and the chicken cost $12.00 for a total of 30+12 = $<T>add(30, 12)=42 spent at the butchers.
