3. How much money do you save when you buy a 340 video game that is on sale for 25%<br> off?

Rudik [331]

£/$340
25% is 1 over 4 and that gives us divide by 4
So what you want to do here is divide 340 by 4 which gives us £/$85
You save around 85 if I’m correct please tell me if I’m wrong :)

A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long

erica [24]

Answer:

Option A , C ,D

Step-by-step explanation:

A nonrefundable deposit required for the day-long program = $50

Charge per person = $4.50

Let us suppose the number of students is s

So, Charge for s students = $4.50s

Let c denotes the total cost

So, total cost : $c=50+4.50s$

So, Option A is correct : The linear model is f(s) = 4.5s + 50.

Total cost : $c=50+4.50s$

We are given that total students are 24

Substitute s = 0

So, $c=50$

Substitute s = 24

$c=50+4.50(24)$

$c=158$

So, Option C and D is also correct.

C. The domain is {x| 0 ≤ x ≤ 24}

D .The range is {y| 50 ≤ y ≤ 158}

Refer the attached figure

The graph is discrete .

So, Option E is incorrect.

Sergio [31]

We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation $y=35795(0.83)^x$ , where x represents the number of years since purchase and y represents the value (in dollars) of the car.
