On a restaurant sign, 14 light bulbs must be replaced. these light bulbs represent 3/8 of the total number of light bulbs on the sign. if b represents the total number of light bulbs, which equation could be used to determine the value of b?

a. 14*b=3/8
b. 3/8+b=14
c. 14=3/8*b
d. 3/8(14)=b

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?
