Given:
The cost C (in dollars) to participate in a ski club is given by,

Where x is the number of ski trips we take.
To find:
The number of ski trips when a total cost of $315 and $485 is spent.
Explanation:
Substituting C = 315 in the given equation we get,

Substituting C = 485 in the given equation we get,

Thus,
If we spend a total cost of $315, we can take 3 ski trips.
If we spend a total cost of $485, we can take 5 ski trips.
Final answer:
• If we spend a total cost of $315, we can take 3 ski trips.
,
• If we spend a total cost of $485, we can take 5 ski trips.
Hello!
<u><em>Answer: x=-9 *The answer must have negative sign*</em></u>
Explanation:
First you had to do is subtract by 4 from both sides of an equation.

Then, simplify.

Divide by -4 both sides of an equation.

Finally simplify.

It change positive to negative sign.

Hope this helps!
Thanks!
Have a great day!

16 % = 38
(16 × 6 = 96
16 / 4 = 4 so = 38/4 = 9.5)
100% = 38*5 + 9.5
=199.5
Answer:
45 kg = Bethan's share
105 kg = Jade's share
Step-by-step explanation:
Let 3x = Bethan's share
4x = Noah's share
7x = Jade's share
Since Noah's share was 60, then 4x = 60
x = 15
3(15) = 45 kg = Bethan's share
7(15) = 105 kg = Jade's share
