Question

Daisy made bread. The equation B = 4f shows the number of loaves of bread baked based on the amount of flour used, where B is the number of loaves of bread made and d is the amount of flour used. Find out the constant of proportionality.

Answer 1

k=4

Explanation:

-The constant of proportionality is defined as the ratio between two directly proportional variables.

-Given that B=4f

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

`y=kx\\\\k=(y)/(x)\\\\\therefore B=4f\\\\(B)/(f)=4`

Hence, B varies directly with f with a constant of proportionality k=4
