Answer:
the answer would be 10
Step-by-step explanation:
because if your multiply 4*5 which is 20 then you divide by 2 the answer would be 10
420 gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get mixture that is 80% antifreeze
<em><u>Solution:</u></em>
Let "x" be the gallons of 90% antifreeze
The, final mixture would contain (x + 60) gallons
Then by given question, we can say,
"x" be the gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get 80 % of (x + 60) gallons
<em><u>Thus we frame a equation as:</u></em>
<em><u>Solve the above equation for "x"</u></em>
Thus, 420 gallons of 90% antifreeze is used
1 shipment = 777 coats
44 shipents = (777)(44)
44 shipments = 34 188 coats
