KatRina [158]

Answer:

14 months

Step-by-step explanation:

Given

Gator's = $105 monthly charges

Tidal Wave = $375 registration fee + $80 monthly charged

Required

Determine for how many months Gators is cheaper

Let the number of months be x;

Represent the given data, algebraically.

For Gators: 105x

For Tidal Wave: 375 + 80x

Represent the above as a n inequality

Since Gators has to be cheaper; we have

$105x < 375 + 80x$

Collect Like Terms

$105x - 80x < 375$

$25x < 375$

Divide both sides by 25

$x < 15$

<em>This implies that Gator's will be cheaper for months less than 15</em>

<em>Hence, the number of months is 14</em>
