To rent a jet ski at hayden’s cost is $25 plus $3 per hour. at austin’s, it costs $5 plus $8 per hour. at how many hours will the rental cost at both shops be equal ?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
