walking tour is $15
boat tour is $18
Answer:
B.
Step-by-step explanation:
$22843.75
I'm assuming that $18.275 is $18,275
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 18275 × 0.05 × 5 = 4568.75
I = $ 4,568.75
The simple interest accumulated
on a principal of $ 18,275.00
at a rate of 5% per year
for 5 years is $ 4,568.75.
y = (5/4)2^x
The function value increases by a factor of 40/10 = 4 when x increases by 2. The function can be written as ...
y = (reference value)·(growth factor)^((x -reference)/(change in x for growth factor))
y = 10·4^((x-3)/2) . . . . . . using point (3, 10) as a reference
This can be simplified to ...
y = 10·2^(x -3) = 10/8·2^x
