Jack buys 7 bottles of orange juice at the corner store for a total cost of $7.28. If each bottle costs the same amount, how much is 5 bottles of juice?
To determine the cost of 5 bottles of orange juice, we first need to figure out the cost per bottle.
Since Jack buys 7 bottles for a total of $7.28, we can divide the total cost by the number of bottles to find the cost per bottle:
Cost per bottle = Total cost / Number of bottles
Cost per bottle = $7.28 / 7
We divide $7.28 by 7 to find the cost per bottle:
$7.28 ÷ 7 ≈ $1.04 (rounded to two decimal places)
Now that we know the cost per bottle, we can find out how much 5 bottles would cost:
Cost of 5 bottles = Cost per bottle * Number of bottles
Cost of 5 bottles = $1.04 * 5
Now we multiply $1.04 by 5 to get the cost for 5 bottles:
$1.04 * 5 = $5.20
So, 5 bottles of orange juice would cost $5.20.
