Answer:
<u>The butter for one portion of onion costs $ 0.44</u>
Step-by-step explanation:
Let's recall that 1 pound = 16 ounces, therefore we have:
Cost of one pound of butter = $ 4.13
Cost of sixteen ounces of butter = $ 4.13
How much dose the butter for one portion cost?
We can use Direct Rule of Three for answering this question, as follows:
Ounces Cost
16 4.13
1.7 x
**************************
16x = 4.13 * 1.7
16x = 7.021
x = 7.021/16
x = 0.44 (Rounding to the next cent)
<u>The butter for one portion of onion costs $ 0.44</u>
One car 40 miles /gallon
other car 30 miles/gallon
..
Total miles = 165
gas used = 45 gallons
...
let first car drive x miles
second car drive y miles
..
x/40 + y/30 = 45
(30x+40y)/30*40 = 45
30x+40y = 45*40*30
30x+40y=54,000
