Answer:
To rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20
Step-by-step explanation:
Since both shops charge the same amount for each kind of vehicle, we will assign variables to the their cost. The cost of a jet ski will be "x" and the cost of the kayak will be "y". Therefore we can create a system of equations as shown below:
Will's shop:
12*x + 9*y = 780
Fun Rentals:
7*x + 11*y = 570
We can isolate "x" on the second equation, we have:
Applying this value on the first equation:
Applying the value of "y" we found on the "x" equation above, we have:
Therefore to rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20
Answer:
The class interval is: 20-30
Step-by-step explanation:
Let l be the lower class limit and u be the upper class limit.
Then according to given statement that class mark is 25
And
Class size is 10
So, the second equation will be:
Adding equation 1 and 2
Now putting u =30 in equation 1
A class interval is written in the form that lower limit comes first and upper limit comes second.
So,
20-30
Hence,
The class interval is: 20-30
