A group of t tourists visits a museum. Thirty of the tourists go to see a planetarium show. The remaining tourists are divided evenly into 4 groups to tour the exhibits. How many tourists are in each group that tours the exhibits? A (t-30) Tourists
B ( t/4-30) Tourists
C 1/4 (t-30) Tourists
D 1/4 (t+30) Tourists

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the answer is 40.

proof:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
