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
I got 47 because...
Tn = Tn-1 + 3×2^(n -1)
Using the above formula,
T2 = 2 + 3×2^(1-1) = 2 + 3×2^0 = 2 + 3 = 5
T3 = 5+ 3×2^(2-1) = 5 + 6 = 11
T4 = 11 + 3×2^(3-1) = 11 + 12 = 23
T5 = 23 + 3×2^(4-1) = 23 + 24 = 47
$24 in 6 hours.
6 hours = $24
1 hour would be: $24/6 = $4
8 hours would then be: $4 * 8 = $32.
So he would make $32 in 8 hours.
Hope this explains it.
