Question

3) David goes into a candy store with $5.00. He buys 9 peppermints for $0.15

Answer 1

Write an equation that will match the story problem​

$x=(5 - (9 \times 0.15) ) \div 0.25$

Solution:

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 = $5 - 9 \times 0.15 = 3.65$

Each sour candy cost $0.25

Now the number of sour candies bought is:

$3.65 = 0.25 \times x$

x = 14.6

Thus david can buy 14 sour candies

Thus the equation that will match the story problem​ is:

$x=(5 - (9 \times 0.15) ) \div 0.25$

Where, "x" means number of sour candies bought
