x=−247
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8<span> is a rational number because it can be written as the fraction </span>8/1. <span>In mathematics, a </span>rational number<span> is any </span>number<span> that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a </span>rational number. ... A real number<span> that is not </span>rational<span> is called irrational.</span>

Then the critical values for this case are:
40 + 5x = y
X is how many weeks she saves
Y is the total savings after 12 weeks
Plug in 12 into the x
40+5(12) = y
40 + 60 = y
100 = y
She will have saved $100 after 12 weeks
