Answer:
Alfredo paid $40.35
Step-by-step explanation:
To work this out you would first have to divide 60 by 100, which gives you 0.6. Then you would multiply 0.6 by 97, which gives you 58.20. This is because you are working out what 60% is. Then you would minus 58.20 from 97, which is 38.8. Then to find out the tax you would divide 4 by 100, which is 0.04 . Then you would multiply 0.04 by 38.8, which is 1.552. Then you would add 1.552 to 38.8, which is 40.352. Then you would divide it to two decimal places, which is 40.35.
1) Divide 60 by 100.
[tex]60/100=0.6[/tex]
2) Multiply 0.6 by 97.
[tex]97*0.6=58.20[/tex]
3) Minus 58.20 from 97.
[tex]97-58.20=38.8[/tex]
4) Divide 4 by 100.
[tex]4/100=0.04[/tex]
5) Multiply 0.04 by 38.8.
[tex]0.04*38.8=1.552[/tex]
6) Add 1.552 to 38.8.
[tex]1.552+38.8=40.352[/tex]
7) Round 40.352 to 2 decimal places.
[tex]40.35[/tex]
