Question 183080
First, write the equations for each situation:
{{{A = 110+0.25x}}} Where x = the excess cost cost medical bills.
{{{B = 190+0.2x}}} Where x = the excess cost of medical bills.
You need to find the value of x for which B is less than A, so...
{{{B < A}}} or...
{{{190+0.2x < 110+0.25x}}} Solve for x by subtracting 110 from both sides.
{{{80+0.2x < 0.25x}}} Now Subtract 0.2x from both sides.
{{{80 < 0.05x}}} Finally, divide both sides by 0.05
{{{1600 < x}}} or {{{x > 1600}}}
Giselle would save with plan B if she had more than $1600.00 + $190.00 = $1790.00 in medical bills.
