1. Ryan bought a book for $25. If Ryan paid 5% sales tax on the book, how much tax did he pay?
2. Tonya borrowed $1500 for one year. If the interest rate was 8.5%, find the total amount Tonya paid back.
Set up the proportion for me please.
We don't really need any proportions here
1.
Cost of book + 5% * cost of book = final price
25 + .05 (25) = $26.25
2.
Amt borrowed + 8.5% * Amt borrowed = Amt Paid Back
1500 + .085 (1500) = $1627.50
can you set up the proportion please
+11
