First, you need to find the trend line that you are going to use before you can answer question 9 and 10.

To do that select 2 points from your list and find the y = mx + b equation.

After you have your equation, all you need to do is plug in the values that you are given for x. Evaluate the expression and you will have your answer.

Answer:

The answers to the question are as follows

A bottle of water costs $2.00

A gallon of mik cots $4.10 and

A bag of chips costs $1.00

Step-by-step explanation:

To solve the question, it is important to note that it is a word problem hence we read the question carefully to clearly understnd and be able to interprete the message from any perspective

We list out the variables as follows

Number of gallons of milk = 3

Number of bottles of water = 6

Number of chips bags = 8

Bill before tax = $32.30

Price of a bottle of water = twice the price of a bag of chips

Price of a gallon of mlk = $ 2.10 + price of a bottle of water

Therefore in order to find out how much each item costs let us call the price of bottle of water $x say

This means that the price of a bag of chips = x/2 and

The price of a gallon of milk = x + $2.10

Therefore we have by multiplying the prices of the items to their respective quantities and summing up

$(6x + 3(x+2.1)+ 8 x/2) = $32.3

This gives by expanding the values 6x+3x+6.3+4x =32.3

13x+6.3 =32.3

13x = 32.3 - 6.3 = 26

Dividing both sides by 13 gives

x = $2.00

This means that a bottle of water costs $2.00

A gallon of mik cots $2.00+$2.10 = $4.10

A bag of chips costs x/2 which is equal to $2.00/2 = $1.00

Steps:

1: p=0.2

2: n = 17

3: n*p= 17*0.2=3.4

Description:

The person will spend less than 20 or o.2 as seen in the question. Meaning p will equal 0.2. P for probability. Now n is for number. n will equal 17. And then we have to times all the number. N times P will equal 17 then times it by 0.2= Answer will come as 3.4.

Answer: 3.4
