Answer 1

Dear Student,

Total rent paid by Maria is given by -

Total rent = initial fee + hourly rent

70 = 10 + time × 7.5

70 - 10 = time × 7.5

60 = time × 7.5

Time = 60/7.5

Time = 8 hours

From this, Maria rented kayak for 8 hours.

Thanks dear. Hope this helps you...

Answer 2

$\fontsize{18}{10}{\textup{\textbf{Maria can rent kayak for 8 hours.}}}$

Step-by-step explanation:

Let Maria can rent the kayak for x hours.

Then, according to the given information, we have

$10+7.50\times x=70\\\\\Rightarrow 10+7.50x=70\\\\\Rightarrow 7.50x=70-10\\\\\Rightarrow 7.50x=60\\\\\Rightarrow x=\dfrac{60}{7.50}\\\\\Rightarrow x=\dfrac{6000}{750}\\\\\Rightarrow x=8.$

Thus, Maria can rent the kayak for 8 hours.
