Karla has spent $42 on food. She bought milk, cheese, and meat. The milk cost half as much as the cheese and the meat cost four
Alina [70]

M = milk

C= cheese

X=meat

milk = 0.5c

meat = 4c

cheese = 1c

<span>4 +0.5 = 1c  = 5.5c</span>

 

C= 42/5.5 = 7.64

X = 7.64 x 4 = 30.56

M =7.64 * 0.5 = 4.67

 

30.56 + 3.82 + 7.64 = approximately $42
