Question 1131834

Snacks are only ${{{5}}}, and is a one-time payment.

Renting a paddle boat is ${{{4}}} per hour. Let {{{hour = h}}}

You have ${{{13}}} in all

{{{13 = 4h + 5}}}

Isolate the {{{h}}}. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract {{{5}}} from both sides:

{{{13 (-5) = 4h + 5 (-5)}}}

{{{4h = 13 - 5}}}

{{{4h = 8}}}

Divide {{{4 }}}from both sides

{{{(4h)/4 = (8)/4}}}

{{{h = 8/4}}}

{{{h = 2}}}

{{{2}}} hours is your limit for the amount of hours you can ride with ${{{13}}} and after buying snacks.
