The 20% increase will be 2 more glasses of lemonade. So therefore now being 12 glasses of lemonade will be multiplied by 9hrs with result of 108 glasses- this will be the total number of glasses sold
If one glass costs $0.50 then the total costs will be
108 glasses × $0.50
answering=$54.00
<span>5t=3b+660....and ... 2t+5b=450
from the first we can see that t=(3b+660)/5 and using this value in the second...
(6b+1320)/5+5b=450 making all have common denominator..
6b+1320+25b=2250
31b=930
b=30...and since 2t+5b=450
t=150</span>
