It is the end of the semester, and the clubs at school are recording their profits. The Science Club started out
with $20 and has increased its balance by an average
of $10 per week. The Math Club has saved $5 per
week after starting out with $50 at the beginning of the
semester.
al. Choose the equation below which represents the
balance the science club has. Let x represent the
number of weeks and y represent the balance of the
science club's account

y= 20 + 50x

y= 20 + 10x

y= 10 + 20x

y= 10 + 10x

y=50 + 5x

Y=5 + 10x

In a graph with several intervals o data how does a constant interval appear? what type of scenario produces a constant interval?

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?
