It's the third choice because a biconditional statement is an "if and only if " statement, using all the same words in the original statement.
I believe the answer is D. $34.43
Ally ran 5 miles in 36 minutes.
Ally's speed is (5 miles)/(36 minutes) = 0.13888 miles per minute.
At that speed, Ally would run 6 miles in (6 miles)/(0.13888 miles/min) = 43.2 minutes.
Ally runs faster than Sami, so Sami must take longer to run 6 miles than Ally.
The only time that is longer than 43.2 minutes is 48 minutes.
The amount you would pay altogether if you borrow $500 for 5 years at
an annual interest rate of 7% is $945.
<h3>How much would you pay altogether?</h3>
The amount you would pay altogether is the sum of the amount borrowed and the interest.
Total value of the debt = interest + amount borrowed
Interest = $700 x 7% x 5 = $245
Total value of the debt = $245 + $700 = $945
