Fred had a garden. The number of flowers in the garden can be determined by the equation: F= 2b, where F is the number of flowers and b is the number of bulbs Fred has planted. Find the constant of proportionality.

Constant of proportionality = 2

Step-by-step explanation:

F = 2b (given)

This indicates that F is directly proportional to b

That is, F ∞ b

Removing the proportionality sign, F = kb where k is the constant of proportionality.

Comparing this with F = 2b, we have that k = 2

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
