A phone service charges a one-time connection fee of $0.33, and $0.05 for every minute (m) the customers talk. Suzy wants to make a call using the ...
service from a pay phone, but she only has $0.90 to spend.
Which function can be used to determine the maximum number of minutes Suzy can talk?
O
.
Use the function C(m) = 0.33 + 0.05m, and solve C(m) = 0.90. O Use the function C(m) = 0.05 + 0.33m, and find C(0.90).

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?
