You can buy 5 items for $10, how much will it cost for 8 items?

Answers

Answer:

$16

Step-by-step explanation:

Looking at the Price for 5 Items (10 dollars), That means the Price Per Item Is 2 dollars. Now we know the Cost per Item, We need to multiply the Cost per item by 8 (2*8) making it 16.

Cost of 5 items = $10

Cost of 1 item = 10/5 =2

Cost of 8 items = 8×2=$16

Therefore, the cost of 8 such items would be $16.
