A certain gym sells two membership packages. The first package, the Die-Hard Package, costs $250 for 6 months of unlimited use. The second package, the Personal Package, costs $130 initially plus $4 each day the member visits. How many visits would a person need to use for each package to cost the same amount over a 6-month period?

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
