Swim flippers are helpful for scuba diving. You can rent them daily for
$15 per day, plus 8% tax. How
much will it cost, including tax, to
rent them for three days?

The answer would be $48.60.

Step-by-step explanation:

Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
