Answer is A. more than 20 let x be number of checks written
let y be monthly cost

plan 1
y=0.30x

plan 2
y = 2.4 + 0.18x

the break even point is when y1 = y2, so

0.30x = 2.4 +0.18x
0.12x = 2.4
x=20

so at 20 checks, the plans will cost same, any checks above that will be cheaper with plan 2.
Answer is A. more than 20

More than 20 checks The Accucheck plan would cost less than the anywhere plan more than 20 checks, the point when they both reach 20 checks, as long as it is in one month period, they will be even. After that, the Accucheck plan will start to cost less and less. here Accucheck: 20 days= 600 cents 30 x 20 = 600 Anywhere Plan: 20 days = 600 cents 240 + 18 (20) = 600 That is how I got it, hope it helps! : ) A.

here
Accucheck: 20 days= 600 cents 30 x 20 = 600
Anywhere Plan: 20 days = 600 cents 240 + 18 (20) = 600
That is how I got it, hope it helps! : )
