Answer:
346 boxes of grape fruit
Step-by-step explanation:
In order to solve this we are going to create a simple system of equations, the number of boxes of oranges will be represented with the letter Y and the number of boxes of grape fruit will be represented with the letter X:
21y + 27x= 18,003
x+y=747
x=747-y
Now we insert that into the first equation:
21y-27(747-y)=18,003
-6y=18,033- 20169
-6y=-2166
y=-2166/-6
y=361
We know that the kiwanis club sold 361 boxes of oranges, now we inster that value into our second equation to solve for the boxes of grapefruit:
x=747-y
x=747-361
x=386
SO they sold 386 boxes of grapefruit.
