Problema Solution
Suppose the sales of a particular brand of appliance satisfy the relationship S(x)=140x+5000, where S(x) represents the number of sales in year x, with x=0 corresponding to 1982. Find the number of sales in 1990
Answer provided by our tutors
for the year of 1990 for x we have
x = 1990 - 1982
x = 8
S(8) = 140*8 + 5000
S(8) = 6,120
the sales for 1990 were 6,120.
