Ok so we can model this like

[tex]1.89+0.25x=3.8[/tex]

This is because the initial price was 1.89$ for the drink, then for every refill, it was a quarter extra. To solve for x we start by subtracting 1.89 from both sides.

[tex]0.25x=1.91[/tex]

So now we divide by 0.25 or multiply by 4 and we get

[tex]x=7.64[/tex]

But x cannot be a fraction. So we round this to the least integer, or 7

The number of times of the soft drink that refills will be 7.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign.

Soft drinks cost $1.89 and refills cost $0.25 each.

With $3.80 to spend on the soft drink and refills.

Then the maximum number of refills will be given as

Let x be the number of refills.

1.89 + 0.25x ≤ 3.80

         0.25x ≤ 1.91

                 x ≤ 7.64
