Dividing by a fraction is equivalent to multiply by its reciprocal, then:
Now, we need to express the quadratic polynomials using their roots, as follows:
where y1 and y2 are the roots.
Applying the quadratic formula to the first polynomial:
Applying the quadratic formula to the second polynomial:
Applying the quadratic formula to the third polynomial:
Applying the quadratic formula to the fourth polynomial:
Substituting into the rational expression and simplifying:
8 percent of 1900 is 152 so 152 of their customers run every day
Answer:
Maria earns 100 dollars
E=100
