It's A. =1n-6
n
Answer: Option B.

Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that

We know that when a = 28 then b = 7. So



Therefore the equation of proportionality is:

So when
then:

Answer: $252.68
Step-by-step explanation:
Find 12.75% of 249 by using formula T= A + (A•I/100)
T=249+(249•12.75)/100)= 31.75 (taxes)
Then add taxes to room cost;
249+31.75= 280.75
Then you’d apply the coupon of 10% by using; Discount = Original Price x Discount %/100
Discount = 10% or 10/100=0.1
Discount = 280.75 x 0.1
= $28.08
Now you’d find the final price by;
Final Price = Original Price - Discount
Final Price = 280.75 - 28.075
Final Price = $252.68
