Mom paid CZK 132.50 for the purchase. She bought bread, 5 kg apples, and three liters of milk. We know that bread costs twice as much as milk, and a kilogram of apples costs 6.50 CZK less than milk. How many CZKs did milk and bread and a kilogram of apples cost?

Correct answer:

a =  30.4 Sk
b =  15.2 Sk
c =  8.7 Sk

Step-by-step explanation:

a+5b+3c = 132.50 a=2b c =    b6.5  a+5 a/2+3 (a/26.50)=132.50 5a=152 a=152/5=30.4

a + 5·a/2+3·(a/2-6.50) = 132.50

10a = 304

a = 304/10 = 30.4

a = 152/5 = 30.4

Our simple equation calculator calculates it.
b=a/2=30.4/2=576 Sk=15.2 Sk
c=b6.5=15.26.5=1087 Sk=8.7 Sk
