Consecutive odd integers are 2 apart
they are
n,n+2,n+4


3(n²)=12+(n+2)(n+4)
expand
3n²=12+n²+6n+8
3n²=n²+6n+20
minus n² both sides
2n²=6n+20
divide bot sides by 2
n²=3n+10
minus 3n+10 both sides
n²-3n-10=0
factor
(n-5)(n+2)=0
n-5=0
n=5

n+2=0
n=-2
has to be odd, so no


n=5
n+2=7
n+4=9


the integers are 5,7,9

For her phone service, Martina pays a monthly fee of $25, and she pays an additional $0.07 per minute of use. The least she has
Mekhanik [1.2K]

Answer: Anything that is 1202 or larger

In other words, m \ge 1202

So we could have m = 1202, or m = 1203, or m = 1204, etc.

===============================================

Explanation:

  • m = number of minutes used
  • 0.07m = amount charged for those minutes used excluding the $25
  • 0.07m+25 = total monthly bill now including the extra $25 fee

The monthly bill is at least $109.14, since this is the lowest amount she has been charged.

\text{monthly bill} \ge 109.14\\\\0.07m+25 \ge 109.14\\\\0.07m \ge 109.14-25\\\\0.07m \ge 84.14\\\\m \ge \frac{84.14}{0.07}\\\\m \ge 1202\\\\

This says that the least number of minutes Martina has used is 1202 minutes.

So if m was a whole number, then m could be selected from the set {1202, 1203, 1204, ...}

Side note: 1202 minutes = 1202/60 = 20.033 hours approximately.
