Question

What is the answer okkkkkkkkkkk

Answer 1

Explanation:

well,

23 < 12 + 0.04×x

11 < 0.04×x

11/0.04 < x

275 < x

x > 275 or x >= 276

so, for more than 275 monthly calls (that means 276 or higher) plan 1 is more economical.

at 275 calls is is plain even between both plans.

for fewer calls than 275 plan 2 is more economical.
