Answer:
f = 2 1/4c
Explanation:
Number of cups of flour is proportional to the number of cakes
Number of cups of flour = f
Number of cakes = c
Therefore,
f = k * c
Where,
k = constant of proportionality
Number of cups of flour = 22 1/2 cups
Number of cakes = 10 cakes
f = k * c
22 1/2 = k * 10
45/2 = 10k
k = 45/2 ÷ 10
= 45/2 × 1/10
= (45*1) / (2*10)
= 45/20
= 2 5/20
k = 2 1/4
The equation is
f = k * c
f = 2 1/4 * c
f = 2 1/4c
