This can be done algebraically:
300*x=330 Where x is the multiplier
Therefore x=330/300=1.1
To find a percentage of a number you multiply by the percentage divided by 100.
So 330 is 110% of 300, which is an increase of 10%.
Answer: J=12
Explanation: To make this equation easier to solve, you can make everything a whole number (a.k.a. Remove the fractions). To do so, you can multiply everything in this equation by the Least Common Multiple (LCM) of all the denominators, which is 12. The equation now becomes:
-4=3J-40
Then, solve it using normal algebra:
-4=3J-40
36=3J
J=12
Much easier, right?!
Hope that helps シ
Answer:
The cost for camping is 266 pounds
The cost for camping per night is 14 pounds
