Answer:
Equation to determine crystals total bill (T) =(7.7+2x) - 1.50
Step-by-step explanation:
Given:
Number of bottles of pop purchased = 4
Number of candy bars purchased = 3
Number of chips bag purchased = 2
Cost of per bottle of pop = $1.25
Cost of per candy bar = $.90
Cost of the coupon = $1.50
To Find :
Equation to determine crystals total bill (T) given the cost of one bag of chips = ?
Solution:
Let the cost of one chips bag be x
Cost of 4 bottles of pop
=>
=>$ 5
Cost of 3 candy bars
=>
=>$ 2.7
Cost of 2 bags of chips
=>
=>$ 2x
Now the total cost of the bill is
T = 5 + 2.7+ 2x
T =7.7+2x
Also Krystal had a coupon worth $1.50, the cost of the ticket will be
T =(7.7+2x) - 1.50
Now, let's do the same as we did for the previous one here.

notice again, how did we get 84 for the 4th element's coefficient? well 36 * 7 / 3. and so on. And you can just expand it from there.
Yes, this is a constant function. This means that f(x) = c (c is a constant function) so no matter what the input is for h(x)=6 is, the output will be 6. Therefore this is a straight line with a slope of 0 and thus a linear function.
Let a,b,c,d and e are five numbers
mean = (a +b+ c+ d+e)/5 = 30
⇒ (a +b+ c+ d+e) = 150_______(1)
now, Let the number excluded be a
then, new mean = (b+ c+ d+e)/4 = 28
⇒ (b+ c+ d+e)= 112
putting this value in (1),
⇒a + 112 = 150
⇒a = 150 -112 = 38
excluded number = 38
The answer should be 380/0.5 =760 speed
