Trees

Along the road were planted 250 trees of two types. Cherry for 60 CZK apiece and apple 50 CZK apiece. The entire plantation cost 12,800 CZK. How many was cherries and apples?

Correct answer:

a =  30
b =  220

Step-by-step explanation:


a+b=250
60a + 50b = 12800

a+b=250
60•a + 50•b = 12800

a+b = 250
60a+50b = 12800

a = 30
b = 220
