Question 547910: Write the equation for the following situation: In one U.S. town, the annual consumption, s, of sugar (in kg per person) can be estimated by adding 30 to half the years, t, since 1975.
Then graph the equation and use the graph to determine the sugar consumption in the year 1991.

given:
+s+=+t%2F2+%2B+30+
here's the plot:
+graph%28+400%2C+400%2C+-2%2C+20%2C+-10%2C+100%2C+%281%2F2%29%2Ax+%2B+30+%29+
s is plotted on the vertical axis
t is plotted on the horizontal axis
Go to +t+=+16+ since 1975 + 16 = 1991
+s+ looks like about 38
