Fruit Punch

For the fruit punch, we intend to buy the fruit punch syrup at Fair price .
which cost us for $4.20

We will buy 4 bottle of the fruit punch syrup.
$4.20 x 4 = $16.80

which after that we just need to buy 7 bottle 1.5litres of mineral water.
For 1.5litres of mineral water cost $0.80
so $0.80 x 7 = $5.60

TOTAL : $16.80+$5.60= $22.40
