Isabel deposits $6,000 into an account that earns 1.5% interest compounded monthly. Assuming no more deposits and no
withdrawals are made, how much money is in the account after 4 years?
Compound interest formula: V(t)= P(1+
t = years since initial deposit
n = number of times compounded per year
r= annual interest rate (as a decimal)
P = initial (principal) investment
V(t) = value of investment after t years
O $6,360.00
O $6,370.78

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
