Answer:
7 is 20
8 is 40
Step-by-step explanation:
Mean is the total of all the numbers divided by the amount of numbers
5:$2.50
9:?
divide 5 by both sides cause you wanna see how much is 1 liter so you can multiply that with 9.
5 divided by 5 is 1.
$2.50 divided by 5 is $0.50
1:$0.50
each liter costs $0.50
Multiply $0.50 with 9 and that is $4.50
the answer is $4.50
