Twenty percent of Country Y’s yearly exports come from fruit exports. One-sixth of all fruit exports from Country Y are orange exports. If Country Y generates $4.25 million from it’s orange exports, how much money does it generate from it’s yearly total of exports?    $21.25 million    $25.5 million    $106.25 million    $127.5 million    $153 million

Set up the problem by translating it into math: Twenty percent of Country Y’s yearly exports come from fruits. Let x equal Country Y’s yearly export value, and f equal the value of its fruit exports:

f = 20 percent of x
f = .2x

One-sixth of all fruit exports from Country Y are oranges. Let y equal the orange export value:          Now that we have our equations, plug in the value given for y (the oranges) and solve:

y = 4.25 million  

Now plug the value for f back into the first equation:

f = .2x

25.5 mil = .2x  

So the fourth choice is correct. Back Next
