If Amy spent her entire pocket money, she could afford 8 candy bars and 8 comic books a week. She could also just afford 10 candy bars and 4 comic books a week. The price of a candy bar is ₹ 5. What is Amy's weekly pocket money?
"W=8br+8bk,"
"W=10br+4bk,"
"8br+8bk=10br+4bk,"
"2bk=br,"
"br=5,"
"bk=0.5br=2.5,"
"W=8\\cdot 5+8\\cdot 2.5=60."
