<h3>Write an equation that will match the story problem</h3>
<em><u>Solution:</u></em>
Given that,
David goes into a candy store with $5.00
Total amount with David = $ 5
He buys 9 peppermints for $0.15 each
And some sour candies. each sour candy costs $0.25
The equation is:
Let the number of sour candies bought be "x"
Then,
Remaining amount after buying pepper mint =
Each sour candy cost $0.25
<em><u>Now the number of sour candies bought is:</u></em>
x = 14.6
Thus david can buy 14 sour candies
<em><u>Thus the equation that will match the story problem is:</u></em>
Where, "x" means number of sour candies bought
