How much would $500 invested at 5% interest compounded monthly be worth after 4 years? round your answer to the nearest cent.

a(t)=p(1+r/n)nt
a.$508.39
b.$610.45
c.$907.68
d.$607.75

500*(1+0.05/12)^(4*12) = 610.45

Hope this helps!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
