The table shows the number of cups of flour, f, that a bakery needs for the number of pound cakes that they make, p.


Pound Cakes, p 3 6 9 14

Cups of Flour, f 8. 25 16. 5 24. 75 ?


Part A

Which equation relates the number of cups of flour to the number of pound cakes that the bakery makes?

f = 2. 75p

f = 0. 343p

f = 2. 75p + 8. 25

f = 0. 343p + 16. 5
