Question

A baker, in 70 minutes, iced 40 cupcakes and, in 49 minutes, iced 28 cupcakes. What is the constant of proportionality?

Answer 1

Answer:

let cupcakes =x (x1=40 ),(x2=28)

minutes =y (y1=70),(y2=49)

k=y/x.... property

=k=.

= 1) k=y1/x1

=70/40

=7/4=1.75

2)k=y2/x2

=49/28

=7/4=1.75

:- the constant of proportionality =1.75
