Thank you! But the last question I don’t understand. Can you please do it again?
The unknown "x" refers to the same amount of cash both of them have before shopping.
The first equation (1) is for Carol, where she spends $1085. After deducting the amount spent, she has "y" amount of money left.
The second equation (2) is for Grace, where she spends $345. After deducting the amount spent, she has "6y" amount of money left because she has 6 times more than Carol.
So just put the (1) equation into (2) equation to find the "x".
