Tim has developed a money saving strategy that uses the formula S=450+100r.
a. Give a possible interpretation of Tim's strategy.

b. What do the slope and S-intercept of the graph of the relation represent, base on the interpretation from part a.?

c. If Tim plans to stop his savings once he has accumulated $1250, what are the domain and range of this relation.

 A) For 100R, that might mean every week, he is putting 100 dollars away for an interpretation.
B) The Slope represents the time it takes to make 100 dollars, and S represents the total amount of money Tim has.
C) If Tim got to 1250 dollars, it would be 8 for R. So 8 would be the domain and 1250 for the range.

Answer:

Step-by-step explanation:

Given that Tim has developed a money saving strategy that uses the formula S=450+100r.

a) 450 will be savings always and for every r an additional 100 would be saved

b) Slope = 100 represents the increase of S for a unit increase of 1.

S intercept = 450 is the savings even when r=0

c) Since max savings is 1250 and min is 450

Range = (450,1250)

For 450 range, domain r =0 and for range 1250, domain r = 8

Domain =(0,8)
