Kari is comparing the cost of cell phone services. The phone she wants costs $200 at Hillsdale Cellular, and the unlimited calling plan through their carrier would cost $2 per day. At Griffith Electronics, Kari could purchase the same phone for $250 and also get an unlimited calling plan for $1 per day. After some number of days, the two options would end up having the same total cost. How long would that take? PLS HELP

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

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

he answer is x=1x3 because x=1 to x=3
