Question

Toby sells his framed paintings for $20 each. Ishmael sells his paintin
gs for $14 each and charges a flat fee of $18 for framing. How many paintings need to be purchased for Toby and Ishmael to charge the same amount?

hintHint:

  • Hint:
○ Form the equation according to given information..
○ Take variable values as x or any alphabet.
○ Solve the equation to get value of x.

The correct answer is: ⇒ x = 3


    • Step by step explanation:
    ○ Given:
    rightwards double arrowToby sells painting for $20 each
    rightwards double arrowIshamel sell painting for $14 each + $18 for framing.
    ○ Step 1:
    ○ Let after selling x paintings they charge  same amount.
    ∴ amount Toby charge for x paintings will be,
    rightwards double arrow20x
    amount Ishamel charge for x paintings will be,
    rightwards double arrow18 + 14x
    ○ Step 2:
    ○ Equate the amountcharge by Toby and Ishamael after sell of x paintings.
    rightwards double arrow20x = 18 + 14x
    rightwards double arrow20x - 14x = 18
    rightwards double arrow6x = 18
    rightwards double arrowx = 18 over 6
    rightwards double arrowx = 3
    • Final Answer:
    Hence, for purchase of 3 paintings they will charge same amount.

    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.
