Two families go skiing on a Saturday. Together, they spend $95 on pizza at a local restaurant and $65.73 for breakfast. One family purchases two adult lift tickets and four youth lift tickets for $166. Another family purchases four adult lift tickets and five youth lift tickets for $263. How much would it cost two adults and five kids to ski for a day?

$189

Step-by-step explanation:

We can create a system of equations to solve this equation. They are as follows:

In this case, I used "A" to represent adult lift tickets and "Y" to represent youth lift tickets.

We need to get one of the variable (A or Y) by itself in one of the equations. I am going to use the first equation.

Now that we have A by itself we can plug it into the second equation.

We have found Y now lets plug it back into the first equation to find the value of A.

Let's check our variables by plugging them both in to the second equation.

Lastly, we can find out how much it would cost 2 adults and 5 kids to ski for a day, using this equation:

Therefore, 2 adult tickets and 5 kid tickets would cost $189.

Hope this helps!!

i believe that the answer is

b. y-1=-2(x-4)

hope this !

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
