Answer: 5,211 dollars
Step-by-step explanation: Our first approch to this is to find the number of Gala and Honeycrisp(HC) Trees are there.
We are given the number of total trees (81 trees) and the ratio between Gala and HC trees (5 to 4). This means for every set of 9 trees, 5 will be Gala and 4 will be HC. We can create the equation
9x = 81
5x = number of gala trees
4x = number of HC trees
x represents the number of sets of 9 trees so in this case, there will be 9 sets if you solve for x.
9x = 81
divide both sides by 9
x = 9
We can plug this back into the 2 other equations that represent the number of each tree so
5(9) = 45 gala trees,
4(9) = 36 HC trees
This makes sense since 45+36 = 81 so it adds up
Now to find the amount of money just take the amount of each trees we have and multiply it by the pounds each tree made then multiply it by the price each pound makes.
45 gala trees * 25 pounds * 1.52 dollars = 1,710 dollars
and
36 HC trees * 25 pounds * 3.89 dollars = 3,501 dollars
Finally, add both of them up to get the total profit
1,710 + 3,501 = 5211 dollars
