Answer:
The total cost Sue paid is $18.59.
Step-by-step explanation:
Sue bought plastic plates for $3.65, cups for $4.25.
Three boxes of plastic tableware for $0.99 each means total cost for three boxes = [tex]0.99\times3=2.97[/tex] dollars
A plastic tablecloth for $6.75.
Total cost of all items = [tex]3.65+4.25+2.97+6.75=17.62[/tex] dollars
Now on this amount 5.5% sales tax is also paid.
Total amount now becomes:
[tex]17.62+(0.055\times17.62)=18.59[/tex]
Hence, the total cost Sue paid is $18.59.
