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
5 + 2(2) = 5 + 4
5 + 4 = 9
The solution is 9
C x d = total cost
c = $6, d = 4
$6 x 4 = $24
