Kevin has $26 and wants to rent a bicycle at the beach. The bicycle rents for a
base fee of $5 and then $6.25 per hour. What is the most amount of hours that
Kevin can rent the bicycle for?

3.36 hours. Please read the explanation though and make sure you understand my last statement.

Step-by-step explanation:

Will you t to represent time again. $6.25t will represent how much he pays for t amount of time. We must take the $5 base fee into consideration as well. Set up:

$6.25t + $5 = $26

First add like terms to get

$6.25t = $21

Now solve for t by dividing both sides by $6.25

t = 3.36 hours

I do not know if they want the decimal remainder or to the hour. If they want it to the hour, the answer is 3 hours.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
