Cauliflowers 40001

Miss Cabbage sells vegetables in the market. Yesterday, she offered two types of cauliflower - a large one for 25 CZK and a small one for 15 CZK. In the morning, she sold 8 boxes of 20 heads of cauliflower and thus earned 3,270 CZK. How many large and how many small cauliflowers did she sell?

Correct answer:

a =  87
b =  73

Step-by-step explanation:


25a+15b = 3270
a+b = 8·20

25·a+15·b = 3270
a+b = 8·20

25a+15b = 3270
a+b = 160

Row 2 - 1/25 · Row 1 → Row 2
25a+15b = 3270
0.4b = 29.2


b = 29.2/0.4 = 73
a = 3270-15b/25 = 3270-15 · 73/25 = 87

a = 87
b = 73
