Can any body solve this problem please

Answer: $13.7
Step-by-step explanation:
It’s telling you he bought 2.25 pounds of meat, and each pound cost $2.80.
So you need to multiply 2.25 by 2.80 which is 6.30 (6.3).
Mr. Stein pays with $20.00. So you subtract 20.00 by 6.30
And you will get $13.7 or $13.70
Hope this helped.
