This is basically free pts It costs twelve dollars to get in to the fair. Tickets for rides cost extra and are d dollars each.

If Tyra buys 20 tickets, how much would it cost her for the fair?

$12 d + 20

$12 + 20 d

20 d - $12

$12 - 20 d

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?
