Answer:
Marvin spent $5 on a value meal after he earned $0.50 a day for doing chores at home
Step-by-step explanation:
The relationship between two quantities could be additive (In this case, one quantity is a result of adding a value to the other quantity) or multiplicative (In this case, one quantity is the result of multiplying the other quantity by a value).
Multiplicative Relationship is a relationship that shows two quantities expressed as multiples of each other.
It can be written as: y = nx
where y and x are multiples of each other
n is equivalent to the ratio of y to x
Let's consider the options we have:
a) On her diet, Mrs. Jackson lost 5 pounds every month.
y = x -a (a= constant)
y = x-5
There is no multiplicative relationship of a unit rate of 0.5 in the statement.
b) Mila eats 12 cup of yogurt every day.
There is no multiplicative relationship of a unit rate of 0.5 in the statement.
c) Marvin spent $5 on a value meal after he earned $0.50 a day for doing chores at home.
y = nx
n = 0.5
y is the result of multiplication of 0.5 by x
y = 0.5x
d) Manuel has 5 pet turtles. He hopes to add a new turtle to his reptile habitat each month.
y = x+a (a = constant)
y = x +1
There is no multiplicative relationship of a unit rate of 0.5 in the statement.
