Question

A baker uses the equation y=3.5x to find the number of cups, y, of milk he needs to make a number, x, of tres leches cakes. what is the constant of proportionality

Answer 1

the constant of proportionality is 3.5

Step-by-step explanation:

DIrect proportional relationship is in the form:

y = kx

where k is the constant of proportionality

The given equation:

y = 3.5x

comparing both equation:

y = y

kx = 3.5x

dividing both sides by x:

kx/x = 3.5x/x

k = 3.5

Hence, the constant of proportionality is 3.5
