Write an equation that models the approximate caloric need of a girl in terms of her age

Question

The usda suggests that a 10 year old girl needs to consume about 2000 calories per day. Between the ages of 10 and 20, that number increases by 100 calories per year.

Answer 1

Age calories

10 2000

11 2100

12 2200

13 2300

14 2400

15 2500

16 2600

17 2700

18 2800

19 2900

20 3000

the slope is 100/1 = 100

The equation is f(x) = 100(x-10) + 2000

where x=10,11,12,....,20
