Answer:
f(x)=740
Step-by-step explanation:
f(x)=45x+200
If f(12)
f(x) = 45(12) +200
f(x) = 540 +200
f(x)=740
Answer:
<h2>0.05x+11<27 for x<=320</h2>
Step-by-step explanation:
Step one:
Plan 1
charges = $27 monthly
the total charges is expressed as
y=27------1
Plan 2
charges= $11 monthly
extral= $0.05 per call
let x be the number of calls
the total is expressed linearly as
y=0.05x+11--------2
Step two:
equating 12 and 2 we have
27=0.05x+11
collect like terms
27-11=0.05x
16=0.05x
divide both sides by 0.05
x=16/0.05
x=320
the inequality for which plan A is more economical is
0.05x+11<27 for x<=320
