Answer:
NOT proportional
Step-by-step explanation:
y/x = 5/2 = 2.5
y/x = 6/3 = 2
also 7/4 = 1. 75 and 8/5 = 1.6 so:-
They are NOT proportional
1.) x=-9 because
2.) x=16
For this case, the average is the sum of the amounts of the three days divided by three.
We know the earn of Friday and Saturdar. We can assign x to the earn of saturday.
We need to multiply by 3 both sides of the equation.
2181 USD + x USD =300 USD
We need to substrat 2181 USD in both sides.
2181 USD - 2181 USD + x USD =300 USD - 2181 USD
x USD =300 USD - 2181 USD
x USD = - 1881 USD
They need a negative earn in order to have an average earn of 100 USD per day.
1073 USD + 1108 USD - 1881 USD = 300 USD
300 USD / 3 = 100 USD
