Question

Amira and Mandisa sell balloon animals at different stands on the boardwalk. They each use a constant number of balloons per animal.

Answer 1

Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.

Linear equation

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the number of balloons for x animals.

Amira uses 4 balloons for each animal.

For Mandisa, using the table using (20, 225) and (60, 25):

$slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{25-225}{60-20}=-5$

Therefore Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.
