The fries are 500 calories and each burger is 300 calories. 500+300+300=1100
W=-5 because you distribute at the beginning with the 2 variables and you solve that's equation and you will end up with 6w divided by 30 and that's will give u W=-5
We can compare the two units or object performances by that.... even in the case of magnitude lower than zero....
Try going for B because do 8 times 0.50 and 0.25 times 33 = to 12.25
