Apply the law of multiple proportions to the two compounds. For each compound, find the grams of copper that combine with 1.00 g of chlorine by dividing the mass of copper by the mass of chlorine. Then find the ratio of the masses of copper in the two compounds by dividing the larger value by the smaller value.

Multiply width times height times length
The answer is 14 - x.
If she is 14 now, and the question is looking for her age x years ago, it is basically just asking you to subtract x from 14.
It also can't be x - 14, because that means Susie's age is x and the question is asking for her age 14 years ago, and it can't be 14x, because that's 14 multiplied by x.
