If she used 4 cups in her first batch with the 2:2 ratio then she would need to split in half because of the new 3:1 ratio.
Answer:
75 cm
Step-by-step explanation:
Perimeter of smaller rectangle = 45 cm
Perimeter of larger rectangle = 5/3 * 45 = 5*15 = 75 cm
A) The constant of proportionality in this proportional relationship is 
B) The equation to represent this proportional relationship is y = 0.2x
<em><u>Solution:</u></em>
Given that,
The amount Naomi pays each month for international text messages is proportional to the number of international texts she sends that month
Therefore,
This is a direct variation proportion

Let "y" be the amount that Naomi pays each month
Let "x" be the number of international texts she sends that month
Therefore,

y = kx -------- eqn 1
Where, "k" is the constant of proportionality
Thus the constant of proportionality in this proportional relationship is:

Last month, she paid $3.20 for 16 international texts
Therefore,
y = 3.20
x = 16
Thus from eqn 1,

Substitute k = 0.2 in eqn 1
y = 0.2x
The equation would then be y = 0.2x
