Answer:
$4.5.
Step-by-step explanation:
We have been given that at the market 8 apples cost $4.
Let us find the cost of 1 apple by dividing total cost of apples by total number of apples.
[tex]\text{Cost of 1 apple}=\frac{\$4}{8}[/tex]
[tex]\text{Cost of 1 apple}=\$0.5[/tex]
To find the cost of 9 apples we will multiply cost of 1 apple by 9.
[tex]\text{Cost of 9 apples}=\$0.5\times 9[/tex]
[tex]\text{Cost of 9 apples}=\$4.5[/tex]
Therefore, the cost of 9 apples will be $4.5.
According to the question,
Cost of 1 apple will be:
= [tex]\frac{4}{8}[/tex]
= [tex]0.5[/tex] ($)
hence,
The cost of 9 apples will be:
= [tex]0.5\times 9[/tex]
= [tex]4.5[/tex] ($)
Thus the above answer is correct.
