can you help me with this
Alright, Shannon, again, percent means "for each 100." If he normally drinks eight 8 oz bottles of Powerade, then he drinks 64 ounces daily, correct?
If he drinks 12.8, then our fraction is 12.8/64. Set that equal to x/100 and cross multiply.
64x=1280, so x= 20%
Anytime you have percent, remember it's out of 100. Make your fraction and set it equal to x/100 and cross multiply.
