# Apples

School kitchen bought 36kg apples for 12 kc/kg. How many kilograms of apples 1/4 cheaper can they buy for the same money?

Result

m2 =  48 kg

#### Solution:

$c_{ 1 } = 12 \ Kc/kg \ \\ m_{ 1 } = 36 \ kg \ \\ \ \\ t = m_{ 1 } \cdot \ c_{ 1 } = 36 \cdot \ 12 = 432 \ Kc \ \\ \ \\ c_{ 2 } = c_{ 1 } - c_{ 1 }/4 = 12 - 12/4 = 9 \ Kc/kg \ \\ \ \\ m_{ 2 } = t/c_{ 2 } = 432/9 = 48 = 48 \ \text { kg }$
