Answer :
Answer: 63
Step-by-step explanation:
You can set up a proportion cost/weight=cost/weight
[tex]\frac{147}{21} = \frac{x}{9}[/tex] Costs go on the top so x is cost for 9 kg
[tex]x=\frac{147*9}{21}[/tex]
x=63
Answer:
$63
Step-by-step explanation:
First find the cost of bananas per kilogram. To find that, divide $147 by 21
147/21=7
One kilogram of bananas costs $7
Now that you know the cost per kilogram, multiply $7 by the number of kilograms asked in the question, which in this case is 9
7*9=$63
9 kilograms of bananas costs $63
