Question 463865: C chemist has to mix two chemicals, A and B, to make 150 grams of a solution. This solution requires 10 grams of A or every gram of B. If the amount of chemical A is designated as x and the amount of Chemical B is designated y, which of the following pairs of equations will allow the chemist to determine how much of each chemical she will need.
1) x+y=150
x=10y
2) x+10y=150
y+10x=150
3) x+y=150
y=10x
