Angela’s grandfather gave her all the cash he had in his pocket to buy raffle tickets that cost $1
daser333 [38]

In this problem situation:

  • the independent quantity is <em><u>the money</u></em> Angela's grandfather gave her
  • the dependent quantity is the <em><u>number of raffle ticket</u></em> Angela will buy.

An independent quantity is the quantity that affects or brings a change in a dependent quantity.

The dependent quantity is affected by the independent quantity. If the independent quantity changes, the dependent quantity will change.

The dependent quantity is dependent on the independent quantity.

<em><u>Let's relate it to the </u></em><em><u>problem situation</u></em><em><u>:</u></em>

  • The amount of money Angela's grandfather gave her is unknown, therefore, the number of raffle tickets Angela can buy cannot be ascertain.

  • If we know <em>how much Angela's grandfather gave her</em>, we can determine <em>how many </em><em>raffle tickets </em>Angela can buy.

  • This implies that the number of raffle ticket Angela will buy is dependent on how much money her grandfather gave her.

Therefore, in this problem situation:

  • the independent quantity is <em><u>the money</u></em> Angela's grandfather gave her
  • the dependent quantity is the <em><u>number of raffle ticket</u></em> Angela will buy.
