(If you dont care much for the explanation)
ANSWER IS
$131.35
If 1 liter of milk is $17 3/4 we just need to find the cost for 7 2/5.
Since we’re working with money we have to turn the $17 3/4 and 7 2/5 into a decimal so its ($17.75) and 7.40
Anyways we multiply those numbers to find the cost of 7 2/5 liters
( 17.75 x 7.40) and the answer is $131.35
