kim can a rent a boat from company A for $ 120 for the whole day .She can rent the same boat from company B for a fee of $ 40 plus $ 20 per hour . what is the number of hours at which the rental fees will be the same ?
120 - 40 = 80
80/20 = ?
In a survey of 300 students,96 of them said that math is their favorite subject.
To determine the number of hours at which the rental fees will be the same for the two companies, Company A and Company B, we need to equate their total rental fees.
For Company A:
Rental fee = $120 (whole day)
For Company B:
Rental fee = $40 (base fee) + $20/hour (additional fee per hour)
Let's assume the number of hours rented is 'h'.
The rental fee for Company B can be expressed as:
Rental fee = $40 + $20/h * h
Rental fee = $40 + $20h
To find the number of hours when the rental fees are the same, we equate them:
$120 = $40 + $20h
Now, we can solve for 'h'.
$120 - $40 = $20h
$80 = $20h
Dividing both sides of the equation by $20, we get:
h = 4
Therefore, the rental fees will be the same after 4 hours of renting from Company B.
