Question

At the market 8 apples cost $4 how much do 9 apples cost ?

Answer 1

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.

$\text{Cost of 1 apple}=\frac{\ 4}{8}$

$\text{Cost of 1 apple}=\ 0.5$

To find the cost of 9 apples we will multiply cost of 1 apple by 9.

$\text{Cost of 9 apples}=\ 0.5\times 9$

$\text{Cost of 9 apples}=\ 4.5$

Therefore, the cost of 9 apples will be $4.5.

Answer 2

If 8 apples cost $ 4, then (4/8) = 1/2 (or 0.50)....so each apple is 0.50 (or 50 cents)

so if u want 9 apples, u will have to pay : 9 * 0.50 = $ 4.50 <=
