<h3>
Answer: 10 years old</h3>
Work Shown:
s = son's age
(father's age)/(son's age) = 9/2
45/s = 9/2
45*2 = s*9
90 = 9s
9s = 90
s = 90/9
s = 10
The son is 10 years old.
Option 1 equation- 30x+50
Option 2 equation- 20x+75
There is automatically a one time fee of $50 for option 1 and $75 for option 2
1 day:
Option 1- this person pays a total of $80 (because of the one time fee of 50 and 30 per day)
option 2- pays a total of $95 (one time fee of 75 and then an additional 20 per day)
Day 2:
Option 1- $80+$30(daily fee)=$110
Option 2- $95+$20(daily fee)=$115
Day 3:
Option 1- $110+$30=$140
Option 2-$115+$20=$135
They will have to stay a minimum of 3 days for option 2 to be a better deal
Answer:
g(x) = log2 (x) – 1
Step-by-step explanation:
I just did this on Edge
Simplify -2n=14-n
add n to both sides -n=14
n=14
