Sylvester paid $120 to rent a jet ski for 2 1/2
hours. If the deposit was $50 of that amount,
what was the cost per hour to rent the jet ski?
The total cost of renting the jet ski, excluding the deposit, is $120 - $50 = $<<120-50=70>>70.
To convert 2 1/2 hours to decimal form, we divide the numerator (5) by the denominator (2) and add it to the whole number (2).
2 1/2 = 2 + 5/2 = 2 + 2.5 = 4.5 hours.
Thus, the cost per hour to rent the jet ski is $70 / 4.5 hours = $<<70/4.5=15.56>>15.56. Answer: \boxed{15.56}.
Stephanie has 3 3/4 bags of soil to put in her
garden. Each bag of soil will cover 125 3/10 ft 2 .
How many square feet will Stephanie be able
to cover if she uses all these bags of soil?
To convert 3 3/4 to an improper fraction, we multiply the whole number (3) by the denominator (4) and add the numerator (3) to get 15 + 3 = 18/4.
Then we add the improper fraction to get 18/4 + 3/4 = 21/4.
So, Stephanie has a total of 21/4 bags of soil.
To calculate how many square feet she can cover, we multiply the number of bags by the coverage per bag: 21/4 * 125 3/10 ft^2.
To multiply the mixed numbers, we first multiply the whole numbers (21 * 125 = 2625).
Then we multiply the numerators (4 * 3 = 12) and the denominators (4 * 10 = 40)
We have 2625 + 12/40 ft^2.
To simplify 12/40, we divide the numerator and denominator by their greatest common divisor (GCD), which is 4.
We have 2625 + 3/10 ft^2.
Thus, Stephanie will be able to cover a total of 2625 + 3/10 ft^2. Answer: \boxed{2625\frac{3}{10}}.
To find the cost per hour to rent the jet ski, we need to subtract the deposit from the total amount paid, and then divide that by the number of hours.
First, let's find the total amount paid by Sylvester:
Total amount paid = $120
Next, let's subtract the deposit amount from the total amount paid:
Amount paid for renting the jet ski = Total amount paid - Deposit
= $120 - $50
= $70
Now, let's find the cost per hour to rent the jet ski:
Number of hours rented = 2 1/2
Convert the mixed number to an improper fraction:
2 1/2 = (2 * 2 + 1) / 2 = 5/2
Cost per hour = Amount paid for renting the jet ski / Number of hours rented
= $70 / (5/2)
= $70 * (2/5)
= $28
Therefore, the cost per hour to rent the jet ski is $28.
