Savings spending

Helen and Barbara had 1,500 CZK saved together at the end of January. After Helen spent CZK 318 from her savings and Barbara spent CZK 249 from her savings in February, Helen had twice as much CZK saved as Barbara. How much money did they have at the beginning?

Final Answer:

a =  940
b =  560

Step-by-step explanation:


a+b=1500
a-318 = 2·(b -249)

a+b = 1500
a-2b = -180

Row 2 - Row 1 → Row 2
a+b = 1500
-3b = -1680


b = -1680/-3 = 560
a = 1500-b = 1500-560 = 940

a = 940
b = 560
