you plan to go snowboarding this weekend in Pennsylvania. the resort charges $15.75 per hour in addition to a $25 deposit to ren
Ulleksa [173]

Answer:

A. Equation is c=25+15.75x

B. Cost is $88


Step-by-step explanation:

A)

Suppose you rent for x hours and each hour costs $15.75

<u><em>How much would you need to pay?</em></u>

15.75x

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay 25+15.75x

This is the equation of renting a snowboard for x hours.

Equation is c=25+15.75x

  • Where x is the number of hours you rent the snowboard, and
  • c is the total cost

B)

If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.

To know how much it will cost, you simply plug in 4 into x (in the equation):

c=25+15.75x\\c=25+15.75(4)\\c=88

Cost is $88

A survey of 100 high school students provided this
HACTEHA [7]

Answer:

35/100

Step-by-step explanation:

You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.

A coffee shop charges $2.50 for each cup of coffee and $1.50 for a cupcake. Your mom gives you $10 and ask you to buy 5 cupcakes
Dominik [7]

Answer:

\frac{10-7.50}{2.50}\geqc

1 cup of coffee

Step-by-step explanation:

Let's say c = coffee

5 cupcakes would cost 5*1.50 = 7.50

We can make an inequality :

\frac{10-7.50}{2.50}\geqc

Now we can solve the inequality

10 - 7.50 = 2.50

2.50/2.50 = 1

The maximum cup of coffee you can buy is 1

Hope this helps :)
