Calculation of the number of mandarin oranges one can buy for $9
We are given that,
$6 = 4 pounds
Dividing by 6 into both sides, we have,
$1 = 4 / 6 pounds
$1 = 2 / 3 pounds
Multiplying the above equation with 9 on both sides,
$9 = (2 / 3) * 9 pounds
$9 = 6 pounds - - - - - (1)
According to the given question,
1 orange weighs 2 ounces - - - - -(2)
1 pound = 16 ounces
1 pound = 8 × (2 ounces)
Using equation 2,
1 pound = 8 oranges
Using equation 1,
$9 = 6 (8 oranges)
$9 = 48 oranges
Hence, one can buy 48 oranges for 9 dollars i.e. $9.
