- Hint:

○ Form the equation according to given information..

○ Take variable values as x or any alphabet.

○ Solve the equation to get value of x..

- Step by step explanation:

○ Given:

discount on each 12-pack soda = $0.20.

No of pack brought = 4.

total money paid = $4.20.

○ Step 1:

○ Let the original price of 12-pack soda be x.

∴ purchasing price of one 12- pack soda will be,

(original price - discount )

(x - 0.20 )

Total price paid for 4 12-pack soda will be,

(original price - discount ) 4

(x - 0.20 ) 4

(4x - 0.8 )

○ Step 2:

○ As he pays total amount of $4.20.

∴ 4.20 = ( 4x - 0.8 )

4.2 + 0.8 = 4x

5.0 = 4x

x =

x = 1.25

- Final Answer:

Hence, the original price of one 12-pack soda is $1.25.

○ Step 2:

○ As he pays total amount of $4.20.

### Use inductive reasoning to make a conjecture about the sum of a number and itself. Then use deductive reasoning to show the conjecture is true.

Informally, a hypothesis is just drawing assumptions about something based on what you already know and have observed.

A conjecture is formally defined as a based-on-observations, a statement considered true.

Speculation is similar to your opinion about something you follow or perhaps a knowledgeable estimate.

For example, observe the numbers below: 2, 4, 6, 8, 10, and 12. What number would come next? You're probably thinking 14, but What led you to that conclusion, and why? You may have seen the pattern and that the list is counting in twos.

The following number is 14 because the list counts by 2's, according to your hypothesis.

You saw the pattern and concluded without making any claim.
