2,275 barrels of refined oil will be produced from 3,500 barrels of crude oil.
with the information that from 10,000 barrels of crude oil, 6,500 barrels of refined oil are produced, it immediately pops out that from x amount of crude oil, 65% will be refined.
now we need to find what is 65% of 3,500
[tex] \frac{65}{100} [/tex] = [tex] \frac{x}{3,500} [/tex]
to find x, we multiply 65 × 3,500 and that amounts to 227,500
that then is divided by 100 so 227,500 ÷ 100 = 2,275
