Three-quarters 36641

In the bakery, they prepared 616 loaves of two types of bread for the expedition: sunflower bread weighing three-quarters of a kilogram and caraway bread 900 g each. They prepared 7 kg of more than half a ton of bread. How many caraway and sunflower loaves of bread did they ship?

Correct answer:

k =  300
s =  316

Step-by-step explanation:


k+s=616
3/4s + 0.9 k = 507

k+s=616
3/4·s + 0.9·k = 507

k+s = 616
3.6k+3s = 2028

Pivot: Row 1 ↔ Row 2
3.6k+3s = 2028
k+s = 616

Row 2 - 1/3.6 · Row 1 → Row 2
3.6k+3s = 2028
0.17s = 52.67


s = 52.66666667/0.16666667 = 316
k = 2028-3s/3.6 = 2028-3 · 316/3.6 = 300

k = 300
s = 316
