Answer:
Step-by-step explanation:
Hi Arie,
Solution:
270 - 30 = 240
They sold 240 apples!
a = 180 - b + c
a + b - c = 180
Move b by subtracting b from both sides.
a - c = 180 - b
Move c by adding c to both sides.
Therefore a equals 180 - b + c.
Answer: (3√5-4√2)(√125) = 75 - 20√10
since 20% is 100
then 80% is 400
Therefore 500 in total to begin with.
