solmaris [256]

You must go to the water park for 8 days to make buying the season pass worth it.

<em><u>Explanation</u></em>

Suppose, the number of days you must go to the water park is  x

Admission for the park is 17.50 per day. So, <u>the total cost for x days</u> will be:  17.50x

Given that, the season pass cost 125. So, the equation will be.....

17.50x=125\\ \\ x=\frac{125}{17.50}=7.142...\\ \\ x \approx 8

<em>(As the number of days can't be in decimal)</em>

So, you must go to the water park for 8 days to make buying the season pass worth it.

750 split in to the ratio 7:8
Alex787 [66]
Given:
total = 750
ratio = 7 : 8

We need to get the ratio of the number to its total

7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.

We multiply these ratio to the total of 750

7/15 * 750 = 350
8/15 * 750 = 400

7:8 is equal to 350:400
