Question

From years 2000 to 2007, the number of

coffee shops in a county increased by 100
shops per year. In 2002, there were 1,500
coffee shops.
Which equation gives the relation between the
number of coffee shops, c, and year, t, where
t=0 represents year 2000.
a) 1,300+100t
b) 1,300-100t
91,700 + 100t
d) 1,700-100t

Answer 1

Answer: A

Explanation:

first, find the amount of coffee shops in year 2000, the "starting point"

1,500 - 100 - 100 (going back 2 years) = 1,300

as the amount of shops is increasing, the slope must be positive, so the answer is A
