Meat

Half a kilogram of pork and three-quarters of a kilogram of beef cost total 5.1 USD. One-quarter of a kilogram of beef and 1 kilogram of pork cost 4.9 USD. Find the price of 1 kg of each type of meat.

Correct answer:

x =  3.84 USD
y =  4.24 USD

Step-by-step explanation:


0.5 x + 3/4 y = 5.1; x + 1/4 y = 4.9

0.5•x + 3/4•y = 5.1
x + 1/4•y = 4.9

2x+3y = 20.4
4x+y = 19.6

x = 96/25 = 3.84
y = 106/25 = 4.24
