What easy math question that gives you the answer 251,521

answer:

200+51 and 500 +21 bam ez

step-by-step explanation:

hope i ; -;

y = 50(1-0.18)ˣ, or y = 50(0.82)ˣ

explanation:

this can be represented as an exponential growth equation,

y = a(1+r)ˣ, where a is the original amount, r is the rate of increase (or decrease) and x is the amount of time.

for this problem, a = 50 since it is the original amount of cologne.   the cologne decreases by 18% each day; r = 18% = 18/100 = 0.18; since it is decreasing, r = -0.18:

y = 50(1+-0.18)ˣ

combining the numbers in parentheses gives us

y = 50(0.82)ˣ
