Answer:
$90
Step-by-step explanation:
Let’s find the avg if 20 and 40 to get an apron estimate on the number of glasses she sold in an hour:
20+49/2=60/2=30
She sold about 30 glasses in an hour
For 6 hours we would have to do:6*30=180
About 180 glasses in 6 hours
To find how much money she made:0.5*180=90
Hope this helps!
