Cathryn went on a 3 day round trip hike at matterhorn peak mountain. the first day she hiked 3 miles. the second day she hiked 2 1⁄2 miles and the last day she hiked 3 miles. how many feet did she hike?

just get this app called photo math it should be able to do those

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
