Hi my name is Vanessa. I think I may know the answer to your question. Please know that I started to learn this about a few weeks ago, and I am still learning. I think the answer is 6 units.
Show Your Work: AB equals 18 units and AD equals 12 units. 18 units - 12 units = 6 units.
*Please let me know if I got the answer right or wrong!! Thank you!!!!
2 burgers and a soda the soda cost 2 dollars since sale tax was added to his meal at the rate of 10% so 20 cents added 19.80 minus 2.20 (I cant think cause im being rushed lol) which equals 17.60 divided by 2 8.80 dollars each
