Question

Josh spent 50 dollars on six coffees and four bagels. The coffee is 3 dollars more than the bagel, find the price for each item.

Answer 1

Jawab:

coffee price = 6,2$

bagel price = 3,2$

Penjelasan dengan langkah-langkah:

If:

C = Coffee

B = Bagel

Then:

6C + 4B = 50$

If 1C = 1B + 3$, then:

6 (1B + 3$) + 4B = 50$

6B + 18$ + 4B = 50$

10B = 32$

1B = 3,2$

If 1B = 3,2$, then:

1C = 3,2$ + 3$

1C = 6,2$

∴ coffee price is 6,2$ and bagel price is 3,2$.
